People will have activities, and they will feel tired when they have activities. At this time, sleep is particularly important. People can synthesize a new protein while sleeping. This kind of protein can relieve physical fatigue and energy consumption, which is a kind of physiological activity to rest the body. Dreaming while sleeping can eliminate useless information in your brain, because you don't have to receive external information, so you can restore your brain power. Moreover, dreaming can establish a good neural communication system and promote the development of brain tissue. So dreaming is good for health.
Finishing information
The human brain will receive a lot of information in a day, and the brain needs to record and identify them consciously or unconsciously. At the end of the day, people's brains will produce a lot of information. When they dream, they can play back the stimuli generated by these information one by one and store them in different memory spaces according to different contents. The most common sentence is "thinking day and night, dreaming at night". What you think during the day often appears in dreams. In fact, the brain is sorting out the information generated by thinking content.
Regulating psychology
Everyone has psychological ups and downs, and emotion is everyone's emotional change. No matter having nightmares or dreaming, the emotional changes brought to us are psychological adjustments. The meaning of dreams lies in the satisfaction of desires. A person's hidden desires may not be satisfied in real life, but they can be psychologically satisfied in dreams, which is very conducive to adjusting psychological balance.
Dreaming is good for health. If a person can't dream, or doesn't have a dream, then his desires, big and small, have nowhere to put, and his mental health is threatened. In addition, the brain is not really relaxed, and memory and all aspects of ability are easily degraded.
