dreaming is a normal and essential physiological and psychological phenomenon of the human body. Many people think it’s a bad phenomenon that dreaming makes the brain unable to rest during sleep, but in fact, proper dreaming is also good for the body.

first, relieve fatigue and rest the body

fatigue is the depletion of energy after physical and mental activities. The energy of the brain mainly depends on blood to supply glucose. Physical and mental activities require a lot of glucose. If the glucose supplied from the blood can not meet its needs, it will use the body’s reserves at this time. One of the processes that the body uses to produce lactic acid. Lactic acid accumulation is a physiological and biochemical manifestation of fatigue. Sleep can relieve this fatigue. When you fall asleep, all activities stop, muscle consumption decreases, and your body temperature decreases in order to save energy.

when people sleep, another function is to synthesize new proteins. Most of the new proteins needed by the human body are synthesized during sleep. Therefore, sleep is essential to relieve fatigue and rest the body.

second, organize information and bring insight

we experience many things during the day. Our brain should record, monitor and record everything around you from time to time. Whether you are conscious or unconscious, especially with a large amount of visual information, as long as you sweep your eyes, all the stimuli will run into your brain. When you sleep, the brain will play back, play back and organize at the same time, and then put it into different functional circuits of the brain according to different contents.

in addition, the brain has the function of learning at night. For example, a famous strange case in the west, the detective couldn’t figure out how the case happened during the day. As a result, he dreamed at night. What was the matter with the dream? The next day, according to the hint of his dream, he solved the case. Like this, in night sleep, dreams sometimes bring insight and sometimes innovation.

third, adjust psychology

we know that if we had a good dream the night before, we will feel energetic and comfortable the next day. However, if you have a nightmare and feel unhappy the next day, you will feel that you have not slept well, and you will feel anxious, irritable, lose your temper, and can’t calm down. It can be seen that dreaming is an essential link to maintain a good attitude.

from the perspective of psychoanalytic psychology, the meaning of dream lies in the satisfaction of desire. Whether you are a noble person or a humble person, there are too many desires that are willing or able to speak and unwilling or unable to speak in the deep layer of our hearts. Many of these almost endless desires cannot be met immediately or at all in unrealistic life. In real life, the desire that can not or cannot be satisfied can obtain psychological satisfaction in the dream and adjust the psychological balance.

if there is no dream, then we can’t sleep well because of large and small desires. Even if we sometimes feel uneasy and anxious in our dreams, we can make dreams and sleep right.
