CHEATING DREAMS

A 36 year old woman had the following recurring dream:

“I’ve been having dreams over the last 5 years that my husband is cheating on me. He is a really good guy and gives me no reason to suspect that he actually is, but when I wake up the dreams feel so real it scares me and I don’t know what to do.”

Dreams of being cheating on are quite common, and like with this dreamer they can make us feel very scared when we wake up, or very mad at our partner even though they didn’t actually do anything! Since the dream had been recurring for 5 years, I asked this dreamer if anything had changed 5 years prior, since recurring dreams are usually linked to something in our waking life. She said that was around the time he took a job requiring a lot of travel. By doing some more detective work we sleuthed that the dreams did indeed correlate with his business trips, either while he was away or about to leave. Dreams of cheating usually indicate that we are feeling cheating out of time with our partner. His travels became ‘the other woman’ in her dream world. Working with and understanding these recurring dreams, and sharing them with her husband, prompted them to plan special ‘date nights’ and carve out more time together while he was in town. This both reassured her psyche and fortified their relationship. After this awareness, and the consequent action they took to remedy the situation, she no longer had the recurring dreams even when he left town.

In another version of the ‘cheating dream’ sometimes we are the ones doing the cheating! For example, a different woman had a dream that she was cheating on her boyfriend. She had recently taken up a new hobby and was spending a lot of time in classes and practice groups for her new interest. Her boyfriend was not only fine with it, he was very actually very supportive of her pursing a passion and he enjoyed her newfound enthusiasm. However, she had some old programming that said it wasn’t OK to take care of her own needs while in a relationship. These old messages triggered feelings of guilt, which then created the dream story of her cheating on her boyfriend. We are all living unconscious stories that can be very strong drivers for how we run our lives. When we break the script of our story, even though it may be in a very healthy way, it can feel like we are doing something ‘wrong’ even though it is very right in the sense of enhancing our quality of life and our sense of connection to self and other. This dream brought to light her old programming and caused her to re-evaluate it, while at the same time it prompted her, like the previous dreamer, to add more quality time with her boyfriend to her busy schedule.

While these dreams may cause us to wonder ‘is my partner really cheating?’, or ‘am I a bad person for dreaming that I cheated?’, usually this dream is a metaphor. If you have reasons to believe your partner is actually having an affair, then do your homework to find out the truth so you can either put your mind at ease or make the necessary decisions to address the situation and take care of yourself. However, in the majority of cases this dream is a symbol of feeling like something is interfering with the relationship, but that something is not necessarily another person.

Whether it is our self or our partner who is the ‘cheater’, anything that feels like it takes away from our relationship can translate to the symbol of cheating. Factors such as working a lot of hours, caring for a family member, excess time spent on electronic devices, even physical or mental health issues such as chronic illness or depression can feel like they are taking away from our relationship. Our dreaming mind cares deeply about our relationships, and will show us when we need to tend to them to fulfill our spirit’s longing for connection. If you have this dream theme, consider it a message to explore the ways in which connection may have been compromised, and use it as a catalyst to repair and spend more time with the person you love.

UNHEALTHY EATING

A 14 year old girl had the following dream:

 “I have recently been having recurring dreams that I am eating unhealthy food in very large portions.”

When I asked the dreamer if she had any ideas of what this dream might mean to her, she stated that she had been on a strict diet and was not consuming very much food at all. She said that she often felt hungry in waking life, and was especially pre-occupied with not eating anything that might be considered unhealthy. In the dream she felt anxious, and she reported sweating a lot in her sleep.

So, what do we make of this dream? Is it occurring because she has been depriving herself of food in waking life, or is it symbolic of something else? The only way to know is to check with the dreamer, since any dream can have a variety of possible interpretations. And, in this case, we actually do have a little bit of dream research to back us up as well. Studies have been conducted in which people were deprived of food, then monitored in a sleep lab to see what they were dreaming about. Can you guess? Yes, they dreamed about food. This very much fits with the above dreamer’s waking life experience. However, why did she dream of eating unhealthy food, rather than a sumptuous, nutritious feast? A different person under similar circumstances might dream of eating all of their favorite foods and experience pleasure, rather than anxiety, around it.

This young woman was putting a great deal of energy into not only eating sparsely, but into eating only healthy foods. She developed almost a fear of eating something unhealthy and ‘falling off the wagon’ so to speak. This theme can also show up in the dreams of recovered alcoholics, addicts, and former cigarette smokers. It is a reflection of the fear of going back to the old ‘unhealthy’ ways, and a reminder not to. What a relief to wake up from that dream. So, in this sense, the dreams are reflective our young dreamer’s fears as well.

What about the night sweats? The anxiety? It is very plausible that sweating in her sleep and the feeling of anxiety in the dream could have been physically triggered by low blood sugar from simply not eating enough before going to sleep. Whatever the body experiences physically can be incorporated into our dreams.

Aside from any biological basis, it is always important to look at emotional connections as well. I have seen many dreams about eating unhealthy food that have more to do with unhealthy relationships, or participating in things – not necessarily food related – that are ‘unhealthy’ for us in other ways. The food in these instances is a metaphor for something else. We explored this angle and the dreamer could not connect anything to her current waking life, so we came to the conclusion that in this case it was the hunger factor that caused the dreams, and the desire for health combined with low blood sugar that created the story of eating unhealthy food and feeling anxious about it.

Working with this recurring dream theme proved to be an eye-opening experience for the dreamer. She came to her own awareness that, while healthy eating was very important to her, perhaps she was taking the food deprivation part to a bit of an extreme in a way that was actually not healthy for her. Our dreams will show us where we are off-balance, and give us clues about how to restore balance. My belief is that we all have this knowledge within us, and our dreams are an amazing portal to access this information. I love to facilitate the process, but the dreamer comes to their own awareness by connection with their deepest and true self, and it is an honor to be part of the experience.

Dreams love the use of puns and plays on words, as well as visually depicting both puns and verbal expressions. When listening to a dream I always have my radar up for any type of pun or imagery that might indicate another layer of meaning. Following are some examples.
A woman dreamed she was kissing a man, and much as she wanted it to be a good kiss his upper was sticking out in such a strange way that it just would not move. This image had her stumped and took some time to decipher. Eventually she said “why would his upper lip be so stiff?” and that’s when the light bulb went off! If you asked this dreamer what it meant to have a ‘stiff upper lip’, she might not have been able to tell you with her conscious mind as this was not a saying she used. However, when we explored the standard meanings of the phrase, it clicked. It turns out the person she was attempting to connect with was experiencing hurt feelings, yet trying to hide them. In this case it was not a romantic partnership, as kissing can be a symbol for connection of any kind. This was an employee she was interacting with on a work project, and her subconscious mind had clearly picked up that he was trying very hard not to show his hurt feelings regarding constructive feedback she had recently given him on how to improve his work. Even though consciously she was not sure she knew what the expression ‘stiff upper lip’ meant, her subconscious mind knew very well and found a visual way to illustrate this verbal saying. She was then able to show some compassion for her colleague and give him as much positive feedback as possible, in addition to ways to improve when necessary. The dream revealed emotional dynamics that were going on under the surface, in a way that allowed her to repair and improve their professional relationship going forward.
A man applied to a job for which he was exceptionally well qualified. He later found out that a friend of the boss – who was not as well qualified – was hired instead. That night the man had a dream that his friend Rob got the job instead of him. Since his friend Rob did not actually apply for the job or work in the same field in waking life, I asked the dreamer if he felt ‘robbed’ because he did not get the job. He said “Absolutely yes!” It’s always interesting to look at the names of people and things to see if they might double as words with another meaning. They don’t have to be spelled the same, as the non-linear mind does not care about logical things like spelling. For example, names of people such as: Mark, Jean, Melody, Bill, Rusty, Crystal, June, Hunter, and Patience can hold double meaning. Names of inanimate objects, and even car models such as Triumph, Fury, Swinger, and Dart can also hold another layer of significance.
A single woman who was looking for love had a dream she was checking the mail. Based on other factors in the dream, I asked her if it was possible she was ‘checking the male’ population around her, as in checking them out. It fit with the rest of the dream and what was relevant for her, and we had a good laugh.
A man found out I work with dreams and casually told me he had a dream that he was peeing on his neighbor. Since this was not a private session I just asked him quickly “Well, are you ‘pissed’ at him?” He laughed and said “YES!”
Now here is some fun for you. Look at the illustrations below…can you decipher the visual puns that are depicted? To find the answers, scroll to the bottom of the article, below my bio.

Shared dreams, also known as mutual dreams, are when two or more people share a dream experience at the same time. The degree to which the dream is shared can vary, from having common elements or events that happen in each person’s dream to the entire dream being the same. The experience is known by different names including mutual dreams, shared dreaming, dream meshing, or linking. Shared dreams can happen spontaneously, or can be incubated and planned, and are most common between people who are emotionally close such as couples, siblings, parent-child, or best friends. Twins may be especially prone to shared dreams, though it may happen between complete strangers as well. We may not hear about this as often, since the strangers would have to later meet and compare their dreams. Following are some of the ways in which this fascinating phenomenon may manifest.

One person is having a dream – already in progress – when another person suddenly pops in, invited or uninvited. The second dreamer (the one making the ‘guest appearance’) may have had the first person strongly on their mind before sleep, and may or may not have any conscious awareness of the dream visitation, let alone remember the encounter the next day upon waking. Similarly, the first person – who was just minding their own dream business – may or may not remember the visit by their guest who popped in.

People often ask when they dream of another person, does it mean that person really came to visit them, or was that person thinking or dreaming of them, too? This is an especially common fascination when the person we dream about is a love interest or former partner with whom we wish to rekindle. While not the norm, nor highly likely, it actually is possible. Often these types of dreams will reflect our feelings about the person in the dream. The dream may outline relationship dynamics, or the person may even represent a part of our own psyche. One distinguishing characteristic that may provide a clue as to the nature of visitor (actual person’s consciousness vs. dream character) is the ‘popping in’ effect, or interrupted quality of a dream that is already happening. This has been a documented phenomenon in psychic dream research, as well as after death visitation dreams, and is one of the markers of a visitation type experience. Intuitive signals are also commonly described as thoughts, feelings, or visions that ‘pop’ into our consciousness in the same manner. One way to verify would be to check in with the other person, which may or may not be possible especially if the other person does not recall any dreams from that night. This still does not rule out the possibility of the occurrence.

MESHING

Meshing refers to the basic level of shared dreams where some of the elements overlap, but the entire dreams of the different people are not exactly the same. The dreams may share common characters, settings, or story lines, which the dreamers may or may not have had actual waking life experience with.  Sometimes sharing a common waking experience can contribute to dream meshing. For example, if two people watched the same movie one night and then both dreamed about some of the characters or settings. Or perhaps they shared an experience, such as going to a museum, and both dreamed about some of the things they saw or experienced at the museum but the entire dreams were not exactly the same. Meshing dreams may be incubated by sharing an experience, then talking about it before sleep, and finally intending to dream about the experience.

MEETING

Meeting dreams are where two or more people interact in the dream world and communicate with each other. This experience is less common than meshing dreams, and it does imply telepathic communication between dreamers. I have experienced this personally, and will share one story to illustrate. My sister and I were on a camping trip, sleeping in the same tent near each other. I woke myself up by talking in my sleep…and then my sister answered me. I thought ‘oh how embarrassing, I fell asleep while we were talking!’, but as I gained wakeful consciousness I looked over and she was actually fast asleep. I tried saying something else to her, curious if she would respond again from her sleeping dream state, but this time she did not. I later learned that being in the same brainwave state may be conducive to facilitating these types of experiences. When we have R.E.M. dreams we are predominantly in the alpha brainwave state, and when we wake up beta brain waves usually take over. This theory fits with my experience that we were able to talk in our sleep (both being in alpha brain waves), but when I woke up I was no longer ‘reaching’ her as I was in a different brain wavelength state.  The next day I asked her if she remembered any dreams. She said yes, and told me the first half of the dream. When it matched exactly what I had dreamed, I stepped in and finished the dream by telling her the rest of it as I had experienced it. She said ‘how did you know?!” I explained to her how I woke up and we were sleep talking together, so I suspected we were sharing a dream and now it was confirmed.

SHARED & PRECOGNITIVE

In the dream my sister and I shared, there were some people and experiences that actually happened the next day! We both dreamed of meeting brothers, and both of us dreamed a specific name of one of them, and the next day we met these people; even the name was confirmed. This is not a common feature of shared dreams but I mention it to show the layers possible with any type of unusual dream phenomena.

GROUP DREAMING

Group dreams are the same as meshing or meeting dreams, but with more than two people partaking in the experience.

SHARING DREAMS WITH ANIMALS

While I have mentioned that shared dream experiences may happen between two people, or even a group of people, it can also happen between people and their animals! Again, one of the facilitating factors of shared dreams, or any type of telepathic sharing, is a close emotional bond. So it makes sense that people who share a close bond with their animals might also share dreams with them. A woman had a dog who she called Leo because to her he looked like a little Lion. One night she dreamed that she was in her living room, and there was a little lion (about the size of her dog!) sitting on her couch, playing with a toy. As she woke up, her dog was making funny sounds and appeared to be also dreaming. He woke up shortly, and proceeded to venture straight out to the living room, jumped up on the couch, and looked as though he were searching for something in the exact spot the woman saw the little lion playing with his toy. While we cannot ask the dog what he was dreaming about, it seems likely they were dreaming of the same thing, each from their own perspective of human and animal. Another man was away on business and left his dog with a friend. The plan was for the dog to stay in the house with her. But one night he dreamed that his dog was in a barn with farm animals. He called his friend the next day, and she told him that his dog had escaped from the house the night before and spent the night in the barn!

INTENDING TO SHARE A DREAM

While any of the above types of shared dreams can occur spontaneously, they can also be intended. As mentioned regarding meshing dreams, sharing an experience, talking about it before sleep, and intended to share a dream can help facilitate mutual dreaming. If people wish to meet in a dream, it’s a good idea to choose the place where you want to meet before going to sleep. It could be somewhere familiar to you, that you know and love, or somewhere you’ve never been. Once you choose the place, you can also pick a code word that you will say to each other. This is not necessary, just a technique if you should chose to use it. As you are each drifting off to sleep, really focus on the meeting place, the other person, your connection with them, what you’d like the interaction to be like, etc. If you find your mind meandering on to another topic, redirect your focus back to the meeting place, the person, the feelings you wish to have, and so on. When you wake up, have each person record their dream independently of the other, either via a recording device or by writing it down. Then you can verbally compare notes, but since the nature of dreams are slippery and they do fade away from us quickly I recommend recording independently first so as not to influence each other’s recounting, but also we may capture details that we may later forget.

Because of the fact that so many people do not remember their dreams, and even vivid dreamers rarely recall every dream from every night, I believe the types of experiences described in here, as well as many other psi dreaming phenomena, may be occurring a lot higher rate than we imagine.

The following article talks about how blind people have a free running circadian rhythm; in other words their wake/sleep cycle is not affected by light as with people who can see.
Below is the title and link to the article:

Entrainment of Free-Running Circadian Rhythms by Melatonin in Blind People

Robert L. Sack, M.D., Richard W. Brandes, B.S., Adam R. Kendall, B.S., and Alfred J. Lewy, M.D., Ph.D.

N Engl J Med 2000; 343:1070-1077October 12, 2000DOI: 10.1056/NEJM200010123431503
http://www.nejm.org/doi/full/10.1056/NEJM200010123431503

Hypnogogic State – The transitional, twilight state between being awake and falling asleep. In this state it is common for paranormal phenomena to occur, including auditory and/or visual hallucinations, out of body experiences, sleep paralysis and sleep paralysis attacks.

Hypnopompic State – Same as the hypnogogic state, except this term refers to the transition from sleep to waking.

Out of Body Experience (O.B.E.) –  When a person’s consciousness leaves the body and is able to observe the physical surroundings such as the bedroom they are in.  This may also involve travelling around, yet still viewing the physical surroundings as we know them in waking reality.

Near Death Experience (N.D.E.) – (a form of O.B.E.) A person may be pronounced clinically dead, only to later come back to life later.  Many will report conversations they overheard (for example between surgeons at the operating table if they died in a hospital) that are later confirmed, and the person would have had no way of knowing this information otherwise. This brings up the interesting and fascinating distinction between mind and brain, as consciousness (mind) is surviving without and beyond the death of the physical matter (brain).

Astral Projection –  When consciousness leaves the physical body and travels, similar to an Out of Body Experience, but the travel is through a more dream like, other worldly realm.

Lucid Dreaming – Becoming aware of the fact that one is dreaming during the experience of having a dream.  For more information read Robert Waggoner’s fascinating book “Lucid Dreaming”.  For more info, go here: https://www.thedreamdetective.com/faq.html#lucid

After Death Contact (A.D.C.) – When a deceased loved one comes to visit us in our dreams.  While some dreams of loved ones who have crossed over are ways of processing our loss, other are reported as feeling very ‘different’ than regular dreams. Some of the hallmarks of A.D.C. dreams are that they feel very real, as if the loved one were actually with the dreamer.  The dreamer may report smelling grandma’s perfume or grandpa’s cigar, and often the dream takes place in the dreamer’s bedroom, which is not the case for most dreams.  Sometimes a dream ‘already in progress’ may be interrupted by the appearance the deceased loved one, who almost always brings messages of comfort and love in any of these scenarios.  Many people also have these dreams of former pets who have crossed over as well.

Shared Dreams or Mutual Dreaming – The experience of having the same dream at the same time as another person.  Usually this occurs between people who are emotionally close such as siblings, close friends, family members or romantic partners. The degree of the ‘shared’ experience may vary from part of each person’s dream being the same (overlapping), to the entire dream being identical for both dreamers.  People sometimes intend for a shared dream experience, visualizing it and agreeing on a meeting spot before going to sleep.

Sleep Paralysis – In R.E.M. sleep our body becomes paralyzed so that we don’t physically act out what we are dreaming about, as this could be very harmful to our self and others.  When we wake up the paralysis releases, however sometimes there is a ‘glitch in the system’ where the paralysis takes a little longer to release.  Becoming conscious and finding that the body is paralyzed can be a terrifying experience that about 20-30% of the population will experience at some time. However, it usually resolves itself and is nothing to be afraid of.

Sleep Paralysis Attacks – A phenomenon that sometimes occurs during the state of sleep paralysis, where the dreamer reports a visitation. The visitor is most often described as either a dark, shadowy figure, or something know as ‘the old hag’, who is reported to look something like a Halloween witch. This phenomenon has been reported all over the world through out history.  Researcher David Hufford wrote a book about this called ‘The Terror that Comes in the Night’.

Nightmares – Scary dreams that often will wake us up with a pounding heart and covered in sweat.  These are R.E.M. dreams and are important to pay attention to when working through life’s difficulties.  If a nightmare relives a trauma and repeats with no progression or resolution over time, this would indicate a P.T.S.D. nightmare and professional guidance with an experienced professional is recommended.

Night Terrors – Different than a nightmare, these do not occur in R.E.M. sleep, but rather in stage 4, or the deepest, non-dream sleep. Often night terrors cause the sufferer to scream out loud, but upon waking they will have no recollection of any kind of dream or what happened.

Daydreams – A relaxed state (similar to a hypnotic trance) where creativity, imagination, problem solving and learning consolidation occur.  As part of our circadian rhythm (similar to the 90 minute cycles between R.E.M. dreams when asleep), we have a natural tendency to daydream about every 70-120 minutes through out the day.

Precognitive Dreams – Dreams that pick up on potentials for the future that may or may not play out. There have been reports of people who have had a precognitive dream and later recognized a dangerous situation in waking life because of the dream.  They were then able to make a course correction to prevent the potential negative outcome because the dream provided them with the warning and awareness to do this.

Clairvoyant Dreams –  A dream during which the dreamer is able to witnesses an outside event (happening in waking reality) at the same time it is actually occurring.

Empathic telepathy –  Similar to a clairvoyant dream, except that instead of witnessing an event as an outside observer during the dream, the dreamer experiences the event as if it were happening to them – in a sense assuming the identity of someone that the waking life event is actually happening to.

We tend to speak in generalized terms of dreams happening in the unconscious (or subconscious) mind, or how it happens mostly in the right (intuitive) brain and that the left (logical) brain goes ‘offline’ during sleep (with exceptions such as lucid dreaming).  While these generalizations may apply, it is much more complicated than that. There are many parts of the brain involved during REM dreaming and the different stages of sleep.

If you have ever been curious about what parts of the brain are active during dreaming, here is an amazingly comprehensive article written by Bob Hoss:

I have been waiting for this day! Here is a fascinating article by Jesus Diaz. I would LOVE to watch my dreams played back on a video some day! Of course, this won’t capture the feelings/emotions, sounds, smells, tastes, etc. that happen in dreams, but the visual component of dreaming is huge. How fun would this be? Read the article to learn more:

Scientists Reconstruct Brains’ Visions Into Digital Video In Historic Experimenthttp://gizmodo.com/5843117/scientists-reconstruct-video-clips-from-brain-activity

Scientists Reconstruct Brains’ Visions Into Digital Video In Historic Experiment
  UC Berkeley scientists have developed a system to capture visual activity in human brains and reconstruct it as digital video clips. Eventually, this process will allow you to record and reconstruct your own dreams on a computer screen.
I just can’t believe this is happening for real, but according to Professor Jack Gallant—UC Berkeley neuroscientist and coauthor of the research published today in the journal Current Biology—”this is a major leap toward reconstructing internal imagery. We are opening a window into the movies in our minds.”
Indeed, it’s mindblowing. I’m simultaneously excited and terrified. This is how it works:
They used three different subjects for the experiments—incidentally, they were part of the research team because it requires being inside a functional Magnetic Resonance Imaging system for hours at a time. The subjects were exposed to two different groups of Hollywood movie trailers as the fMRI system recorded the brain’s blood flow through their brains’ visual cortex.
The readings were fed into a computer program in which they were divided into three-dimensional pixels units called voxels (volumetric pixels). This process effectively decodes the brain signals generated by moving pictures, connecting the shape and motion information from the movies to specific brain actions. As the sessions progressed, the computer learned more and more about how the visual activity presented on the screen corresponded to the brain activity.
An 18-million-second picture palette
After recording this information, another group of clips was used to reconstruct the videos shown to the subjects. The computer analyzed 18 million seconds of random YouTube video, building a database of potential brain activity for each clip. From all these videos, the software picked the one hundred clips that caused a brain activity more similar to the ones the subject watched, combining them into one final movie. Although the resulting video is low resolution and blurry, it clearly matched the actual clips watched by the subjects.
Think about those 18 million seconds of random videos as a painter’s color palette. A painter sees a red rose in real life and tries to reproduce the color using the different kinds of reds available in his palette, combining them to match what he’s seeing. The software is the painter and the 18 million seconds of random video is its color palette. It analyzes how the brain reacts to certain stimuli, compares it to the brain reactions to the 18-million-second palette, and picks what more closely matches those brain reactions. Then it combines the clips into a new one that duplicates what the subject was seeing. Notice that the 18 million seconds of motion video are not what the subject is seeing. They are random bits used just to compose the brain image.
Given a big enough database of video material and enough computing power, the system would be able to re-create any images in your brain.
 In this other video you can see how this process worked in the three experimental targets. On the top left square you can see the movie the subjects were watching while they were in the fMRI machine. Right below you can see the movie “extracted” from their brain activity. It shows that this technique gives consistent results independent of what’s being watched—or who’s watching. The three lines of clips next to the left column show the random movies that the computer program used to reconstruct the visual information.
Right now, the resulting quality is not good, but the potential is enormous. Lead research author—and one of the lab test bunnies—Shinji Nishimoto thinks this is the first step to tap directly into what our brain sees and imagines:
Our natural visual experience is like watching a movie. In order for this technology to have wide applicability, we must understand how the brain processes these dynamic visual experiences.
The brain recorders of the future
Imagine that. Capturing your visual memories, your dreams, the wild ramblings of your imagination into a video that you and others can watch with your own eyes.
This is the first time in history that we have been able to decode brain activity and reconstruct motion pictures in a computer screen. The path that this research opens boggles the mind. It reminds me of Brainstorm, the cult movie in which a group of scientists lead by Christopher Walken develops a machine capable of recording the five senses of a human being and then play them back into the brain itself.
This new development brings us closer to that goal which, I have no doubt, will happen at one point. Given the exponential increase in computing power and our understanding of human biology, I think this will arrive sooner than most mortals expect. Perhaps one day you would be able to go to sleep wearing a flexible band labeled Sony Dreamcam around your skull. [UC Berkeley]
