Dreaming situation in animation
Dream is a subjective experience, an imaginary image, sound, thinking or feeling produced by people during sleep, which is usually involuntary. The scientific discipline of studying dreams is called the study of dreams.
Dreaming is related to REM sleep, which is a shallow sleep state in the later stage of sleep. It is characterized by rapid eye movement, pontine stimulation, accelerated breathing and heartbeat, and temporary limb paralysis. Other sleep periods may also dream, but rarely. Lack of sleep when entering deep sleep is considered to be related to dreaming. [ 1]
Edit this paragraph overview
Dream is an image language. "Zhuangzi's Theory of Everything" said: "Sleeping is a big dream." These images range from ordinary things to surreal things; In fact, dreams often inspire artistic and other inspirations. German chemist Kekule claimed to dream that a snake was swallowing its own tail and realized the molecular structure of benzene ring. The forms of dreams include waking nightmares and spring dreams that may accompany wet dream.
Most scientists believe that all human beings dream and sleep at the same frequency every time. Therefore, if a person feels that he has never dreamed or only had one dream in one night, it is because his memory of those dreams has disappeared. This kind of "memory erasure" usually occurs when a person naturally and gently enters the slow-wave sleep stage from the rapid eye movement sleep stage and enters the awake state. If a person is awakened directly from REM sleep (for example, by an alarm clock), they are more likely to remember their dreams during REM sleep (but not all dreams during REM sleep will be remembered, because a slow-wave sleep period will be inserted between active sleep, which will cause the memory of the previous dream to disappear).
True dreaming has been directly confirmed only in humans, but many people think that dreaming may also happen to other animals. Animals have been proved to have REM sleep, but their subjective experience is difficult to determine. The animal with the longest average REM sleep time is pangolin. Mammals may be the only dreamers in nature, or at least the most frequent dreamers, because it is related to their sleep patterns.
Some people think that the above explanation of dreams is unscientific. Dreams are just a kind of psychological activity when people are sleeping. The psychological activity in dreams, like the psychological activity when people are awake, is a reflection of objective things in the human brain. The bizarre dream in the dream is the illusion of stimulating various objective things when people are unconscious during sleep. For example, when people are awake and tachycardia, it seems that the palpitation feeling of being chased becomes a bizarre nightmare of being chased, and when people are awake and bradycardia or premature, the palpitation feeling becomes a bizarre nightmare of being hung and falling. In dreams, we often feel slight physiological symptoms that some people can't easily feel when they are awake, which is caused by the fact that the stimulation of external objective things is relatively small, while the stimulation of internal objective things is relatively strong.
Edit this paragraph of psychology
From a psychological point of view, dreams are a window for the conscious to see the unconscious. Freud and Jung were the founders of dream analysis.
Some psychologists also believe that human dreaming is a preview of how the brain handles dangerous situations in a virtual environment. Especially nightmares, human beings have 300 to 1000 nightmares every year. Human beings are trained in safety in nightmares.
A study conducted in 2009 by Carey K. Morewedge, an associate professor at the Tepper School of Business at Carnegie Mellon University, and Michael I. Norton, an associate professor at Harvard Business School, found that dreams have different importance in everyone's mind. The researchers provided students in the United States, South Korea and India with four existing dream theories to choose from, to see their acceptance of each theory.
Theory 1: Freud's theory: dreams reflect emotions buried deep in the subconscious, and those fragments of recalled dreams can help us expose these deep emotions.
Theory 2: Problem solving theory: Dreams are mainly used to process information related to the law of existence. Therefore, dreams can provide us with profound insights and tell us how to solve problems.
Theory 3: Learning theory: Dreams are the process that the brain processes the information it comes into contact with during the day, which helps us to clean up useless information, thus avoiding the confusion of information in the brain.
Theory 4: By-product theory: Dreams are meaningless illusions. This is an illusion produced by the brain when it processes the random pulses of sensory input.
The results show that no matter in which country, people have the highest recognition of Freud's theory and think that dreams have deep meanings. (56% in the United States, 64.9% in South Korea and 73.8% in India. Perhaps eastern culture believes in the subconscious meaning of dreams more. )
The reason for editing this dream
1. At present, the cause and purpose of dreams are still inconclusive in academic circles. Generally speaking, dreams are caused by some nerve impulses released by the brain when processing information and consolidating long-term memory (such as dust raised during cleaning or information flow being processed), which are interpreted by conscious brains as bizarre vision and hearing.
First of all, Hobson and McCarley put forward the theory of "activation-synthesis" in 1977: the pons in the brain stem will constantly send out signals (PGO waves) to stimulate and activate the conscious part of the brain and make it synthesize a meaningful dream.
However, Solms later found that patients with brain stem injury still dream, while patients with parietal lobe injury (parietal cortex responsible for body sensation and sensory integration) do not dream. Perhaps the brain stem is only related to REM dreams, while the parietal lobe is related to REM dreams and NREM dreams. Zhang Jie put forward the theory of "continuous activation" in 2004: one of the functions of sleep is to transform temporary memory into long-term memory, and REM stage deals with unconscious "procedural memory" instead of conscious "declarative memory" in eye movement (NREM) stage. In the REM stage, the unconscious part of the brain is processing programmed memory, while the activity of the conscious part is reduced to a minimum because the sense is cut off. At this time, the information pulse from the memory bank will activate the conscious part and let it weave a dream through association. When another pulse came, I had another dream, and the dream suddenly changed.
In addition, it is believed that the reason or function of dreams is: (1) generating new ideas and strategies through arbitrary mutation and "Darwinian process"; (2) clear the garbage in the brain. Dreams are the last glimpse of garbage; (3) The continuous stimulation of long-term memory, the strangeness of dreams during sleep comes from the storage format of long-term memory, but the awake brain can give it a correct explanation; (4) Connecting distant but related memories and strengthening them into a story; (5) transforming external stimuli into dreams to prevent them from being awakened; (6) Self-satisfaction, reducing psychological pressure; (7) supplying oxygen to cornea through eye movement; (8) ... and many other viewpoints. However, some people in Taiwan Province Province put forward a "psychosomatic theory" of dreams: when dreaming, fantasy and self are separated, and people will not notice that they are dreaming. "Fantasy" is to take data from sensory memory and send it back to the sensory area to form an illusion. The purpose is to use simulated sensory signals instead of real signals to drive autonomic nerves to perform psychosomatic functions. Pain and pressure will drive the "repair nerve" in the autonomic nerve, and the repair nerve will be arranged into many meridians, which will have a chain reaction in the brain and spine. One of the functions of dreaming is to simulate an extremely dense exercise massage signal when growth hormone rises, and drive the meridians to repair the body.
2. Buddhist statement
Dreams are like burps. When people are living and working, they constantly input all kinds of information into their consciousness through their eyes, ears, nose, tongue and body, and transmit it to Araille's consciousness. During the break, Araille hasn't finished processing. When she adds something new, she may give up what she used to add. Once he comes into contact with knowledge like a conveyor belt, he will send these stimulated or squeezed information back to his brain consciousness regularly and irregularly, forming various dreams.

Edit this supernatural explanation
Some people think that dreaming is because the soul leaves the body after falling asleep and travels through time and space, so some people will be shocked by what they see and experience in their dreams in reality. This is the so-called sight.
Edit this lucid dream
Lucid dream, also called lucid dream, means that you can stay awake in your dream and know that you are dreaming.
Some people wake up suddenly when they are dreaming. When they know they are dreaming, they can control their dreams. This is a lucid dream. In a lucid dream, you can control your actions freely, and you can also control the content of the dream at will, even other people in the dream are completely controlled by you.
Edit this paragraph to control dreams.
Although the cause of dreams has not yet been determined, the most scientific explanation at present is some unprocessed shock waves in nerve impulses. These shock waves will make a small part of our brain active from sleep and form dreams after brain processing. In other words, as long as the judging part and thinking part of our brain are also active and can send out stronger shock waves instead of the original shock waves, then we can control everything in our dreams at will, that is, control dreams (commonly known as lucid dreams), including feelings, words and deeds of others, and even violate all physical laws (such as flying).
Controlling dreams requires the dreamer to know that he is in the dream, so as to realize the change. (1) Perception (awakening), people who want to control dreams must first know that they are dreaming, and believe that dreams can be changed at will, thus stimulating the brain to think locally. (2) Change, when the thinking part becomes active, you can change the content of the dream according to your own ideas. However, the dreamer must be firm, otherwise the shock wave from the brain is weaker than the original untreated shock wave, and the content of the dream will not change.
Most people think it is impossible to control dreams, because when people enter dreams, their self-awareness will be lost and they can't judge whether they are dreaming. But according to experiments, people can judge that they are dreaming through training, but the success rate is low. Only about 20% of the subjects can successfully control their dreams within half a year. They point out that although they can change the content of dreams, the scope of change is limited, and generally they can only change one thing that the dreamer focuses on. There are different explanations for this. Most people think that the part of the human brain that can be stimulated during sleep is limited, and it can't handle too many nerve impulses, so most of it is handled by the subconscious. But the experiment can still conclude that dream control can be achieved through training.
Some people think that dream control is actually easy to realize. As long as you tell yourself that this is a dream under unusual circumstances, you can do what you want to do according to your own thinking, accomplish many things that you can't do in real life, and keep remembering the contents of the dream after waking up.
Dreaming of bracelets is a good omen, which indicates that life will be happy.
I dreamed that the bracelet was broken, which was a bad omen.
