Dreaming is a normal and indispensable physiological and psychological phenomenon of human body. After people fall asleep, a small number of brain cells are still active, which is the basis of dreaming. Why do people dream and what happens 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 stop people from dreaming. In other words, when dreaming brain waves appear during sleep, they are immediately awakened to prevent the dream from continuing. The results show that dream deprivation will lead to a series of physiological abnormalities such as blood pressure, pulse, body temperature and skin electrical response ability, and the function of autonomic nervous system will also 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, orientation and so on. Obviously, normal dream activity is one of the important factors to ensure the normal vitality of the body.
