”Some people dream every night, but others hardly dream at all” “Dreaming can delay one’s rest and affect one’s sleep” “If you dream that you are falling and falling on the ground, it may be a sign that you will have All these statements about dreams are wrong. Dreams are neither a manifestation of disease nor a necessary result of insomnia, but a physiological reflection. Basically, everyone dreams, and every day we have strange and weird dreams. From a psychological point of view, why do people dream? And what are the benefits of dreams? This article will tell you some answers about dreams. Dreaming is not resting well? In my daily life, I often hear people ask me: “I dream a lot at night, I don’t sleep at all” or “I didn’t get a good night’s rest last night, I dreamed all night, what should I do to stop dreaming”. As a result, the next day, it seems to feel a little bit low in spirit and energy when studying and working, as if dreaming really delays the rest of the person. Some doctors, according to the traditional concept, also recognize that dreaming is a factor that interferes with the rest of the brain or the performance of bad rest. In fact, this concept is not correct. Because dreaming is not an important indicator to measure the quality of one’s sleep, nor can it be said that dreaming means that one has not slept well. Insomnia as a phenomenon is objective, and dreams as a universal physiological phenomenon is by no means redundant, we recognize the existence of insomnia, but we can not think that insomnia and dream sensation are necessarily linked. Dreams are actually just a universal physiological phenomenon, and many people dream every night, whether you have dream memories or not, or whether you have dream sensations or not. Psychologists have studied our sleep by applying electrodes to the corners of our eyes (to detect eye movements), scalp (to detect brain waves) and chin (to detect muscle tension), and the results show that we go through five stages when we sleep. The first stage is light sleep, from which we can easily wake up. The second stage is a slightly deeper sleep, and the third and fourth stages indicate that we enter a deep sleep, which usually takes about 90 minutes from the start of sleep to the fourth stage. After that, we enter the fifth stage of sleep, rapid eye movement sleep (REM sleep), which is mainly characterized by eye rolling, and most dreams occur during the REM stage. Each night, REM sleep accounts for 20-25% of the entire sleep process – about 100 minutes – and studies have found that if one wakes up in REM sleep, he or she will be able to recall his or her dreams in more than 80% of cases (i.e., dream perception, which mainly refers to one’s recollection of certain episodes of the dream after waking up), while in In other stages of sleep, people forget whether they dreamed and what they dreamed about, or have a mere vague image. People who claim that “I rarely dream” actually spend about 600 hours per year experiencing about 1500 dreams, or about 6 years of their lives dreaming. Many people do not understand the alternating cycles of sleep, the status of dreams in sleep and their physiological role, the difference between dreams and dream sensations, and the fact that dreams or dream sensations do not have any side effects on human health. Many people are blindly caught up in the fear of dreams mainly because of the old traditional concepts and the unscientific interpretation of dreams by feudal superstition. What is the function of dreams? Since dreams are a universal physiological phenomenon, what kind of functions do they have? For this reason, in the past years, many psychologists have given their own evolutionary and chemical explanations for the difficult problem of “dreaming”, but we still have not been able to fully decipher the mystery of dreaming, but through scientific experiments, it has been found that dreaming has many benefits for some organismal activities. Normal dreaming activity is one of the most important factors to ensure the normal vitality of the organism. Scientific workers have done some experiments to block people from dreaming. It was found that the deprivation of dreams can lead to a series of physiological abnormalities in the human body, such as an increase in blood pressure, pulse rate, body temperature and electrical reactivity of the skin, and a decrease in the function of the vegetative nervous system, as well as a series of adverse psychological reactions, such as anxiety, nervousness, irritability, perception hallucinations, memory loss, and so on. It also causes a series of adverse psychological reactions, such as anxiety, nervousness, irritability, perceptual hallucinations, memory disorders, orientation disorders, etc. It is obvious that the normal dream activity is one of the most important factors for the normal vitality of the organism. Dreams are a way to harmonize the balance of the human psychological world, and in particular they have a more pronounced regulating effect on the attention, emotions and cognitive activity of a person. From the point of view of psychoanalytic psychology, the desires that fail or cannot be satisfied in real life can, however, be psychologically satisfied in dreams and regulate the psychological balance. We know that if you have a good dream the night before, you will feel energetic and peaceful the next day. But if you have a nightmare, the next day the mood is not happy, will feel no sleep, will be anxious, irritable, love to lose temper, do things quietly. It can be seen that dreaming is an essential part of maintaining a good state of mind. Since the activity of the right hemisphere is dominant in dreams, and the left hemisphere is dominant after waking up, it is possible to achieve a dynamic balance of neural regulation and mental activity by alternating waking and dreaming during the 24-hour circadian activity of the organism. In addition, those scholars who regard dreams as information processing believe that dreams can help us to filter, classify and consolidate the daytime experiences in our memory, which is conducive to organizing information and improving memory. In one experiment, people who were asked to listen to some uncommon phrases or learn some visual images before going to sleep remembered less the next morning if they were awakened each time when they entered rapid eye movement sleep compared to being awakened in other stages of sleep. At the same time, it is thought that dreaming is a brain process that may also facilitate the integration of information, leading to inspirational epiphanies or groundbreaking discoveries in scientific research or artistic creation. For example, Mendeleev dreamed of the periodic form of many chemical elements, which inspired him to complete the periodic table of elements; the composer Tadini once dreamed that he gave his violin to a devil to play, and actually played a beautiful melody, and when he woke up, he immediately recorded the music played by the devil and created the “Devil’s Song” which has been passed down to the world. So at some point, “put the problem aside and sleep first” may be much better than thinking hard. How to view dreams correctly? Studies have found that many dreams are not sweet at all, for both men and women, and 8 out of 10 dreams are marked by negative emotions. So some people are too worried about interpreting the negative emotions and dreams in their dreams, and are overly concerned about the anxiety of the dream feeling, which leads to a doubling of the dream feeling, which in turn increases the worry about their health and the fear of insomnia, thus forming a vicious circle, which is actually not much necessary, and having nightmares may sometimes just be a working procedure of the brain in regulating emotions and memory. Of course, if you don’t sleep, a nightmare should be a different story. Dreaming should also be like doing other things, there is a degree, excessive will be counterproductive, damaging the physical and mental health of people. Panic and terror dreams often make people wake up from sleep, and it is difficult to fall back to sleep after waking up; strong and deep dreams will leave deep traces in the brain cells, so that the brain does not rest and fatigue. It is generally believed that it is best to dream in order to recall a dream last night and not recall the specific dream the next day. Patients with neurasthenia often have difficulty falling asleep and are often awakened by nightmares, interfering with their normal sleep, making them drowsy and listless during the day, and even by dreams can also produce hypochondria and anxiety disorders, aggravating the development of the disease. It can be seen that, although dreams are a kind of nebulous things, but it has a profound impact on the normal functions of people, therefore, a person to have a good dream, must first have a good state of mind – mental health.
