Psychology is also closely related to dreams. In fact, dreams often turn into scenes when you sleep.
The whole process is normal, and there is no need to worry about dreaming. Knowing the rationality and naturalness of dreams, you will understand that dreams don't need conditioning at all.
"I think every day and dream at night." Dreams are the most common phenomenon in people's lives, so there are different views on the generation of dreams. Some people say that dreams are a continuation of excitement during the day, and some people say that dreams are a manifestation of people's weakness. How do dreams affect people's health? According to relevant data, dreams are beneficial to human health.
First of all, dreams are a sign of health.
The latest research results of doctors confirm that there is no "sleep center" in the human brain as imagined in the past, and dreams are the result of the joint action of various central points in the human brain responsible for various functions. If a central point is destroyed, it will form a dream, or an incomplete dream. In dreams, characters have only words, but no images.
Second, daydreaming is good for body and mind.
In psychology, people's psychological activities with fantasy plots when they are awake are called "daydreaming" or "daydreaming".
From the psychological point of view, daydreaming is an effective way to relax psychological nerves.
Experts who study human mental health say that although the exact mechanism of daydreaming affecting human physical and mental health is still unclear, it is certain that this kind of brain activity has played a benign role in promoting the immune system. On the other hand, "daydreaming" can free the left brain from language activities, make it at rest, and make the right brain give full play to its visual thinking ability, thus eliminating the fatigue of right-handed workers who are good at language thinking.
Third, nightmares are the prediction of diseases.
Dreams are everyone's subconscious psychological reactions. Although dreams are absurd, some of them often reveal clues to physical health.
Psychologists believe that dreams seem to be an instrument that will respond to some unknown physical changes. For example, some hepatitis patients will have anxious and fearful dreams a few days before the onset of the disease, and some patients complain that they feel the right rib injury in their dreams.
The above is just a psychologist's point of view. If people dream slightly, have no bad symptoms, or feel that it will affect their rest, they don't have to consider their health. If you dream too much, it will affect your rest and daytime spirit, or if you have symptoms after dreaming, you still need some necessary treatment. Medical circles have their own conclusions about the relationship between competitive dreams and human health.

There are different opinions about how dreams are formed. Pavlov's higher nervous activity theory holds that dreaming is the product of heterogeneous stages of sleep. In parasomnia's state, due to the increase of cerebral cortex blood flow and oxygen consumption, brain nerve cells are still in very active metabolic activities, and the inhibition state is not deep, and they are still in the so-called "working" (excited) state. In the case of receiving all kinds of internal and external stimuli, the corresponding memory traces will be "resurrected", so all kinds of dreams will be produced.
If you smell perfume or flowers when you sleep, you may dream that you are in a garden full of flowers and fragrant; When cold ice is placed on your forehead, you will dream of a cold winter; When you hear the sound of running water, you will dream of rain; When the face is covered with towels and other things, there will be dreams of choking and stopping breathing. Some people often dream that dogs bite their legs and wake up with a dull pain. After diagnosis, their legs were sick. This is all because the nerve impulses from internal and external stimuli spread to the corresponding nerve centers in the cerebral cortex, thus causing the excitement of nerve cells. If it is a whole day's missing, such as receiving letters from distant relatives, or preparing for exams, I will dream of meeting relatives at night, or nervous about exams. This is because the nerve cells in the corresponding parts of the cerebral cortex are too excited to be fully inhibited during sleep and remain in an excited state. Generally speaking, it is easy to dream when there are many anxieties, fears and desires during the day, when people are tired, fasting and have a high fever, when they are stimulated by sound and physical, and when the air pressure and temperature change obviously. The survey results show that the most dreams belong to vision, followed by hearing, movement, touch and taste. Of course, some dreams overlap, such as dreams in which vision and hearing coexist. There are also colorful dreams in visual dreams, such as red flowers and blue sky, which account for about one tenth of visual dreams.
The content of dreams varies with age and is also related to the richness of knowledge and experience. Different wishes make different dreams: little girls dream of dolls, inventors dream of the completion of inventions; Mother dreamed of seeing a distant daughter and so on. The same stimulus can cause different dreams. Dreams are related to past experiences. Dreams of new experiences in two or three days account for about 75%; Dreams from distant childhood account for about15%; Dreams unrelated to past experiences only account for about 10%.
There are many kinds of dreams. There are six kinds of dreams in China's ancient book "Li Zhouguan's Pure War Dream": "One is a positive dream, the other is a nightmare, the third is a dream, the fourth is a dream, the fifth is a love dream, and the sixth is a fear of dreams." In fact, the content of dreams is not limited to these six categories. Everyone will have all kinds of dreams: dreams of continuing to create during the day, dreams of memories, dreams of fantasy, sweet dreams, dreams of troubles, and so on. Sometimes dreams are too beautiful and happy to be expressed in words, and I can't wait to draw them. Sometimes dreams are tortuous and interesting, just like drama; Sometimes the dream is gloomy and terrible, and I wake up in a cold sweat. In some dreams, we are like bystanders, just like watching a TV series; in other dreams, we are there, participating in the progress of events, crying and laughing, frightened and resentful. He will also be a person who loves love. "Zhuangzi" said: "Fang dreams, but he doesn't know dreams. He dreams in a dream, and then he knows his dream. " Dreams are often illogical. In dreams, the most absurd and contradictory behaviors and events are intertwined in an extremely incredible form. All these are enough to show that dreaming is a low-level brain activity and a manifestation of low-level thinking. When people dream, the corresponding cerebral cortex activity is in a low level of rough activity, and the integration of cerebral cortex response is incomplete. The analysis of things is often wrong, bizarre and illusory, and past events are presented in a chaotic form. Therefore, the content and reason of dreaming are not mysterious, but can be analyzed and explained.
When people are dreaming, although their eyes are closed, their eyes are still turning rapidly. By measuring the eye movements during this "rapid eye movement" period, we can accurately find out the time of dreaming. In this way, it is found that human beings dream for about 90 minutes.
Some physiologists believe that a certain number of dreams are necessary, because it can relax people's higher nervous activity and play a role in buffering, regulating and calming the spirit. They have proved through experiments that shortening the time of dreaming will make people feel impatient and anxious. Some physiological psychologists have concluded that normal dreaming is beneficial to the recovery of human intelligence, because a certain degree of nerve excitement is helpful to the establishment and consolidation of nerve connections.
