Dreaming is an enduring source of mystery for scientists and psychologists. It can be entertaining, fun, disturbing, frightening, and sometimes bizarre.
Besides that, dreams can bring about realizations about how a person feels and think, which can be beneficial for providing personal insight. However, do dreams really have any meaning behind their bizarreness?
Although there are no definitive answers, there are still several types of dreams, themes, and different factors that cause these dreams to occur. Read down further to explore the fascinating space of ‘dreaming.’
Dreams are the images, ideas, emotions, and sensations that usually occur involuntarily in mind during certain stages of sleep. They may seem confusing or perfectly rational, entertaining, fun, romantic, disturbing, frightening, and sometimes bizarre.
Dreaming is still a mystery of human cognition, the neurophysiological correlates of dreaming are still unclear, and many questions remain unresolved because there are no proper ways to investigate the dreaming brain.
However, one thing that comes clear cut: Dreaming can happen anytime during sleep. But the sleeper has the most vivid dreams during a phase called REM (rapid eye movement) sleep.
Nightmares are dreams that are often dull, gloomy, and frightening and involve intense negative emotions. Research has indicated that a stressful event can cause more frequent nightmares, for example, exam stress, natural disasters, and the death of significant others.
And besides the stress of waking life, nightmares can occur because of conflict, fear, trauma, emotional problems, medication or drug use, and illness. However, if the nightmares are recurring and the sleeper, after an episode of a night terror, is awakened completely, is oriented immediately, and remembers the dream vividly, then the individual may have nightmare disorder.
Lucid dreams are the types of dreams where the dreamers become aware that they are dreaming. The dreamers become aware of their dreaming by noticing the bizarre events of the dream.
And contrary to some beliefs, lucid dreaming differs from REM sleep. However, lucid dreaming also constitutes a unique, hybrid state of sleep and wakefulness.
Furthermore, lucid dreamers can remember their dreams after waking. Fascinatingly, they can interpret the dream while dreaming and control it and its sequence of events. Not only can the lucid dreamer exert control over their actions, but they can also decide to interact with the environment, the characters, and the course of the dream.
Vivid dreams are similar to lucid dreaming; however, unlike lucid dreams, the dreamers aren’t aware of the ‘dream.’ Instead the dreams feel more vivid and realistic. And though people can experience dreams in REM and NREM, they are usually most vivid in REM sleep.
These vivid dreams can occur as a nightmare or can seem random. Anyhow, some people regard these vivid dreams as symbols that provide insight into mental health or if the subconscious may be trying to say something. However, there is no evidence to support this. But scientists do recognize that emotions can express themselves in dreams.
There have been many theories about why we dream, but no one knows for sure. Are dreams just a part of the sleep cycle, or do they have any purposes?
Some research states that dreams do not serve any purpose; meanwhile, some say dreams have specific purposes regarding mental, emotional, and physical health. And thus, studies looked into the importance of dreams and speculated that dreaming serves the following functions:
Though dreams can happen in all stages of sleep, they are most likely to occur rather vividly during REM sleep. Following that, there are five stages of sleep in a sleep cycle: wake, 3 stages of NREM (non-rapid eye movement), and the last stage (rapid eye movement)REM sleep.
This phase depends on whether the eyes are open or closed. Then the individual starts feeling drowsy and closes their eyes.
This is the first stage of NREM. In this stage, the brain slows down first, and then the heartbeat, eye movements, and breathing slow down. Finally, the body relaxes, and muscles may twitch a little. This stage lasts for about 1 to 5 minutes before the sleeper moves into the next stage.
This is the NREM Stage 2. During this stage, the sleeper becomes less aware of their surroundings, their body temperature drops, and their eye movements stop. The breathing and heart rate also become more regular.
It lasts for about 25 minutes, during which memory consolidation takes place. It means that the brain gathers, processes, and filters new memories acquired the previous day.
This is the deepest stage of NREM sleep, which is also referred to as delta sleep. During NREM stage 3 sleep, the muscles are completely relaxed, blood pressure drops, and breathing slows down. And the sleeper progresses into the deepest sleep, and then the brain and body repair, restore, and reset for the coming day.
The brain also consolidates memories—for example, general knowledge, facts or statistics, personal experiences, and other things. So if the sleeper is woken up during this stage, they are likely to have ‘dreams’ that are memories from earlier.
This is the final stage; it’s when the REM sleep cycle starts. At this time, the brain’s activity closely resembles its activity during waking hours; the body is relaxed and immobilized, breathing is faster and irregular, and the eyes move rapidly.
REM is also when the sleeper is in a deep sleep and when dreaming or nightmares happen. And similar to NREM 03, memory consolidation also occurs during REM sleep, and it is when emotions and emotional memories are processed and stored.
It’s hard to say for how long dreams last. But experts can provide an estimation about how long a person may spend dreaming.
REM sleep starts after 90 minutes of sleeping and lasts only a few minutes early in the night but gets longer as the person sleeps. And according to a medical research agency, NIH (National Institutes of Health), a person spends about 2 hours dreaming each night.
The theory of dreaming proposes that the sleeping brain is a self-organizing system, combining irregular neuronal signals into a narrative during sleep called dreams. However, Freud regarded dreams as a royal road to the unconscious.
Freud also suggested that studying dreams’ apparent content could lighten the hidden and unconscious desires that lead to neurosis. However, interpreting dream symbols and ascribing meaning to them has become a source of both entertainment and self-reflection.
But what do they mean? Here are 7 common dreams and their Meaning.
Dreaming about falling is quite common. And though there is a popular myth that if the dreamer hits the ground in their dream, then they will die in real life, which simply is not true.
However, a study reported that dreaming about falling is popular and notorious for reoccurring. It is linked with negative emotions such as stress, sadness, or frustration.
Furthermore, the author of The Illustrated Dream Dictionary, Russell Grant, stated, “Dreaming of falling is very common, and it is a symbol of fear in real life, perhaps of failing at work or life.” He adds, “Falling often expresses a need to let yourself go more and enjoy life more.”
The awkward and horror experience of being naked in public is one of the common dream themes. It’s where people dream of showing up at a public place like a school, an office, or the bus stop, dressed inappropriately /nude.
It, too, is said to be linked with negative emotions. And Penney Peirce, the author of Dream Dictionary for Dummies, suggests that dreaming of public nudity might indicate that the dreamer feels like a phoney or that they are afraid of revealing their imperfections and shortcomings.
Dreaming about getting chased or pursued by some stranger or something unknown is quite terrifying. And many people are subjected to these types of dreams.
Tony Crisp, the author of Dream Dictionary, suggests that being chased in a dream might indicate a desire to escape from one’s fears or desires. The key to understanding such a dream might depend partly on the identity of your pursuer. For example, if the chaser is of the opposite sex, then Crisp suggests this means you are afraid of love or haunted by a past relationship.
Death is another common theme of dreaming that can be particularly disconcerting. And sometimes, the dreamer’s dream of the death of a loved one or even of dying themselves.
According to a study, dreams and visions of death are well documented throughout history and culture, along with the impact on the dying person and their loved ones having profound meaning. After a deep analysis of the dreams, six categories emerged: comforting presence, preparing to go, watching or engaging with the deceased, loved ones waiting, distressing experiences, and unfinished business were the themes.
There are dreamers subjected to dreams about taking tests. And according to a British psychic, taking a test in the dreams might reveal an underlying fear of failure.
He writes in his book The Hidden Meaning of Dreams, “Examinations are stressful experiences in which you are made to face up to your shortcomings.” He also states, “To dream of failing a test, being late for one, or unprepared shows that the dreamer feels unprepared for the challenges of waking life.”
Dreaming about teeth falling out or rotting is one of the most common and usual dream themes. And a study aimed to explore whether tooth dreams would be related to a physiological stimulus and what this symbolizes.
According to the findings, teeth falling in dreams may relate to dental irritation during sleep and may be more common in people with depression. Or it has to do with deep personal loss, or just that the dreamer is worried about their attractiveness or appearance.
Flying dreams are pretty exciting, but they can be as terrifying, especially for those afraid of heights. So what does it mean? To answer simply, it doesn’t mean anything.
And according to a study report, some flying experiences in dreams are not accompanied by emotions. However, dreamers self-rate the emotional intensity of flying dreams to compare this dream type with other dreams. And it is stated that the intensity of the negative emotions is pretty high compared to the positive ones.
As flying dreams cannot be explained, many authors have speculated about the possible meaning of flying dreams. Like, Carl Jung, flying dreams symbolise the overcoming of life difficulties; other authors connect flying dreams with waking-life problems like impotence or avoidance. If flying dreams were ever associated with waking life, they often included negative emotions (mild anxiety or fear).
Researchers don’t know why dreams are easily forgotten since the only access to dreaming is dream reports, which are made later during waking life. And can be partial or modified by the waking consciousness.
One cannot measure cerebral activity during/on dreamful sleep versus dreamless sleep. Also, it could be harder to remember dreams during REM sleep since the body may shut down systems in the brain, where the dreamer only recalls dreams that happen just before waking up.
A night of sound sleep and don’t wake up until the morning and are less likely to remember dreams. So, the following are some tips that may help with remembering the dreams:
Dreams may be easier to recall if the sleeper wakes up naturally, but with an alarm, the brain will focus on turning it off.
Before going to sleep, remind yourself that you want to remember the dream. You’d be more likely to remember it if you decided to remember it.
Thinking about the dream right after waking up might be easier to recall the dream.
Dreams are fascinating and mysterious. However, in many cases, it is found that dreams reflect the events or concerns of waking life. And though there are research articles and studies, scientists don’t have all the answers on why we dream or the types of dreams we have, but just some clues.
Also, behind the interpretation of the dreams, what do you think? Are the theories accurate enough?
