Scientific explanation: Scientists have done some experiments to stop people from dreaming. That is to say, when the sleeper has a dream brainwave, he is immediately awakened to stop his dream from continuing, and so on. The results show that deprivation of dreams will lead to a series of physiological abnormalities of human body, such as blood pressure, pulse, body temperature and skin electrical response ability, and the function of autonomic nervous system will be weakened. At the same time, it will also cause a series of adverse psychological reactions, such as anxiety, tension, irritability, perceptual hallucinations, memory disorders, irritability and so on. Obviously, normal dream activity is one of the important factors to ensure the normal vitality of the body.
Some people think that the above explanation of dreams is unscientific. Dreams are just a kind of psychological activity when people are sleeping. The psychological activity in dreams, like the psychological activity when people are awake, is a reflection of objective things in the human brain. The bizarre dream in the dream is the illusion of stimulating various objective things when people are unconscious during sleep. For example, when people are awake and tachycardia, it seems that the palpitation feeling of being chased becomes a bizarre nightmare of being chased, and when people are awake and bradycardia or premature, the palpitation feeling becomes a bizarre nightmare of being hung and falling. In dreams, we often feel slight physiological symptoms that some people can't easily feel when they are awake, which is caused by the fact that the stimulation of external objective things is relatively small, while the stimulation of internal objective things is relatively strong.
