Why do people dream? Is dreaming good or bad

Everyone dreams. About one third of one's life is spent dreaming. In dreams, we may encounter various problems or dreams. Some dreams are very real, as if we have experienced them. Do you know why people dream?

Dreaming is a normal psychological phenomenon in the process of sleep. In general, human brain nerve cells are in a state of inhibition during sleep. Sometimes the inhibition process is complete, sometimes not complete. If it is not completely inhibited and a few nerve cells in the cerebral cortex are excited, people will have dreams. As the saying goes: 'think every day and dream at night'. The root of dreams is actually brain activity. We know that people's brain can respond to external stimuli when awake. In the evening, people are tired, so they enter the sleep state. During most of the sleep process, brain waves and eye movements are the same as those during awakening, and only body muscles are inhibited. At this time, what we have experienced, seen or thought during the day will reappear in our dreams. The content of dreams is often related to the stimulation received during the day or sleep. If you think too much about something during the day, you will dream of it when you sleep at night, or although you have never thought about someone or something, because you have experienced it before, some brain nerve cells will 'recall' the past when you sleep at night, so you will also dream of it. When sleeping, external stimuli will make the brain react incorrectly, so as to have all kinds of strange dreams. In addition, the stimulation and pathological changes of various organs in the body will cause similar scenes in dreams, such as urgent urination and urination, dreaming that there is no toilet everywhere, and so on.

dreaming is a physiological phenomenon. Normal dreaming will not affect your health, but if you often have nightmares or strange dreams and affect your sleep, you should see a doctor for timely treatment. According to relevant information, people spend about 1 / 3 of their life sleeping and 1 / 5 of their life dreaming. If - a person lives for 75 years, he has 15 years of dreaming. Dreaming is a normal physiological and psychological reflection. It's impossible not to dream. You dream every night you sleep. Therefore, people with psychological problems can solve them by interpreting dreams. You feel that you didn't dream last night. It's just that you forget what dreams you had, not No. and you remember the content of the dream because you remember the dream in your heart, It's something that attracts you. It's not impossible to remember that you've had a dream every time you wake up or wake up.

From a biological point of view, dreams are randomly excited by brain stem waves. Personal understanding is that your brain stores a large amount of information, including what you see, hear, experience, feel and even fantasize, that is, your personal consciousness. From the perspective of psychoanalytic psychology, the meaning of dreams lies in the satisfaction of desires. No matter what class you are, you will have your own private desires in your heart, which will be completed through dreams. But dreaming is also good. If we are too tired in a day, it is generally easy to dream. Dreaming can alleviate our fatigue at the end of the day. It can make our psychology peaceful and meet the things that some people think and can't do in reality.
