I didn't do my work well during the day, but I dreamed all night.

Dreaming is a physiological phenomenon, but some people think that dreaming is a bad thing. They think that dreaming makes them unable to get enough rest and will damage their brains after a long time. In fact, this kind of worry and panic is unnecessary. Dreaming has many benefits for people. German neurologist Professor Koth huber believes that dreaming can exercise the function of the brain. He said that only a part of brain cells are active at ordinary times, that is, during intense mental work, only a part of brain cells are active, and the other part of brain cells are dormant. If these dormant brain cells are not used for a long time, they will gradually decline. In order to prevent this decline, the dormant brain cells can only exercise themselves and exercise their functions by dreaming during sleep, so as to achieve the goal of self-improvement and non-decline. Some people think that dreaming may be a working procedure of the human brain. By sorting out the information received by the brain during the day, the information that the brain can't process during the day can be well handled in the dream, and the problems that can't be solved by thinking hard during the day can be solved in the dream at night. For example, Voltaire, a famous Russian writer, often completed the conception of a poem in his sleep. The cyclic structure of benzene molecules was discovered by German chemist Kekule in his dream. According to the EEG test, it is also found that the activity of the human brain during dreaming is quite intense, and we can detect fast and disordered brain waves from dreaming, and its intensity sometimes exceeds that during awakening. From this point of view, dreaming is a self-need to exercise the function of the human brain. There is an ancient saying in China: "Blind people have no dreams, and fools have few dreams." Although this statement is somewhat arbitrary, it also shows from one aspect that people with little knowledge and stupidity rarely dream. On the contrary, dreamers are mostly people with rich thinking and imagination. Of course, if you don't sleep, you will have nightmares, which should be another matter. Dreaming, like doing other things, should have a limit. Excessive dreaming will be counterproductive and harm people's physical and mental health. Panic and horror dreams often wake people up from sleep, and it is difficult to fall asleep again after waking up; Strong and deep dreams will leave deep traces in brain cells, making the brain tired without rest. It is generally believed that the best way to dream is to recall a dream last night the next day but not the specific dream. Patients with neurasthenia often have difficulty falling asleep, and when they finally fall asleep, they are often awakened by nightmares, which interferes with their normal sleep, makes them groggy and listless during the day, and even produces hypochondria and anxiety from dreams, which aggravates the development of the disease. Everyone dreams. But most people forget their dreams soon after waking up, leaving only some feelings at most. Those who still clearly remember the contents of dreams after waking up can only sleep poorly or dream more. Why do insomniacs always say MUBI? I often hear people say, "I didn't have a good rest last night, but I had a dream all night" and "I was in MUBI at night, and I simply didn't fall asleep". Therefore, it seems that I really feel a little depressed and lack of energy when I study and work on this day, as if dreaming really delayed my rest. According to the traditional concept, some doctors also admit that dreaminess is a sign that the brain has never rested or has a bad rest. In fact, this old concept is wrong. Dreaming and recalling dreams is not an indicator of poor sleep, nor can it be said that dreaming means not sleeping well. As mentioned earlier, dreams are a common physiological phenomenon. No matter whether you have dreams or not, you must have 4 to 5 dreams every night. It is an exaggeration to say that you dream all night, and it is unrealistic to say that you don't dream, not to mention that MUBI dreams less. Some people at home and abroad have made physiological tests on insomnia, dreaming all night or MUBI's chronic insomnia, and conducted EEG tracing and research with various physiological instruments. The objective records prove that the sleep cycle of these patients who complain of "MUBI" and "dreaming all night" is no different from that of normal people, and the proportion and actual time of their fast-wave sleep period with dreams have not been significantly shortened or prolonged. The experience of "dreaming all night" and "MUBI" is the same. Others give psychological tests to such patients, and think that this kind of experience has something to do with personality. No matter from the universal law of human sleep or from the results of experimental research, dream feeling and insomnia may not be necessarily related. Whether you have a dream feeling or not and the degree of dream feeling can not be used as an objective indicator of insomnia or not. In that case, why do people always associate dreaming with insomnia? As we have talked about many times before, dream is an inevitable physiological phenomenon and an active physiological process during the fast wave sleep period, which is manifested in the form of expressive components, perceptual memory activities and unconventional associations. The dream sense refers to the memory of some plots in the dream after waking up, or only the impression of having had a dream, and even the content of the dream is difficult to explain clearly. People who complain of insomnia with multiple dreams or insomnia without dreams should refer to the sense of dreams, which is related to emotional factors and personality characteristics. For example, introverts focus more on their inner feelings, sleep is shallow and easy to wake up or wake up, and they can often recall vivid dreams; People who are depressed and anxious are easy to wake up from their dreams, so they feel more dreams and sleep falsely. The researchers also found that MUBI is closely related to the degree of waking up in sleep, and people who report themselves in MUBI on weekdays are more likely to wake up in sleep. In the sleep experiment, as long as the volume of 2 decibels is enough to wake them up, and their dream memories are also high. Clinically, people who often see sudden dreaminess are often related to being hurt by seven emotions, being in a bad mood and sleeping uneasily, so insomnia is often accompanied by dreaminess.
