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. 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.
Dreams are a way to coordinate the balance of human psychological world.
Because the right hemisphere is dominant when dreaming and the left hemisphere is dominant after awakening, the dynamic balance between nerve regulation and mental activity can be achieved by alternately waking up and dreaming during the 24-hour day and night activities of the body. Therefore, dreams are a way to balance people's psychological world, especially for people's attention, emotions and cognitive activities.
Dreamless sleep is not only of poor quality, but also a sign of brain injury or disease.
Recent research results also confirm this view, that is, dreams are the result of the brain's regulatory center balancing various functions of the body, and dreams are the need for the healthy development of the brain and maintaining normal thinking. If the brain's regulatory center is damaged, dreams will not form, or only some incomplete dream fragments will appear. If you sleep for a long time without dreams, it is worth people's vigilance. Of course, if you have nightmares for a long time, it is often a sign of weakness or some diseases.
