Why do humans dream Why do humans dream a lot, and how do dreams appear?

Dreaming is a normal and essential physiological and psychological phenomenon of the human body. After a person falls asleep, a small part of the brain cells are still active, which is the basis of dreams. Why do people dream, and how do they react if they don't dream?

Normal dream activity is one of the important factors to ensure the normal vitality of the body.

Scientists have done some experiments to block human dreams. That is, when the sleeper appears in the brain waves of dreaming, he will be immediately awakened, not to let the dream continue, and so repeatedly, and it is found that the deprivation of dreams will lead to a series of physiological abnormalities in the human body, such as blood pressure, pulse, body temperature and the electrical response ability of the human body have a tendency to increase, and the autonomic nervous system function has been weakened, and it will also cause a series of adverse psychological reactions of people, such as anxiety, nervousness, irritability, perceptual hallucinations, memory impairment, disorientation, etc. Obviously, normal dream activities are one of the important factors to ensure the normal vitality of the body.

Dreams are a way of harmonizing the balance of the human psyche's world.

Since the right cerebral hemisphere activity is dominant in dreams, and the left cerebral hemisphere is dominant after awakening, in the 24-hour diurnal activity of the body, awakening and dreaming alternately, which can achieve a dynamic balance of neuromodulation and mental activity. Therefore, dreams are a way to coordinate the balance of the human psychological world, especially for people's attention, emotions and cognitive activities.

Not only is dreamless sleep not only poor, but it is also a sign of brain damage or disease.

Recent research has also confirmed the idea that dreams are the result of the brain's regulatory center balancing various functions of the body, and that dreams are necessary for the healthy development of the brain and the maintenance of normal thinking. If the regulatory center of the brain is damaged, dreams cannot be formed, or there are only some incomplete dream fragments, and if there is no dreamless sleep for a long time, it is worth people's vigilance. Of course, long-term nightmares are often a sign of weakness or certain diseases.

It's just that your mind is still thinking about things, in short, people who think a lot love to dream.

The brain did not stop working.

The reason why human beings often dream and dream appears is because of what people think in their hearts, what they think in their hearts, and then they never forget, and there must be echoes, so there are such dreams.

The appearance of dreams** is observed in our daily life, such as the images of TV series or movies we watched during the day, and it is very likely to reappear when we sleep and dream at night.

Dreams generally appear in REM sleep, the fifth stage of sleep. At this stage, brain waves are high frequency and low amplitude, which is very similar to brain waves when awake. Freud believed that dreams are the manifestation of the self in the subconscious.
