< p > with the development of modern psychology, the study of dreams is getting deeper and deeper, and the mysterious veil that has been shrouded in dreams for thousands of years has been gradually lifted. 'sleep with dreams contributes to brain health' is one of the recent research conclusions. < / p >
< p > dreaming is a normal and indispensable physiological and psychological phenomenon of the human body. After people fall asleep, a small number of brain cells are still active, which is the basis of dreams. < / p >
< p > according to the study, people's sleep is carried out alternately by positive sleep and abnormal sleep. 80% of the people awakened in abnormal sleep are dreaming, and 7% of those awakened in positive sleep are dreaming. A person's dreams can last for about 1.5 hours every night. < / p >
< p > because dreams are associated with the sleep cycle, people who wake up in abnormal sleep feel more dreams, while those who wake up in positive sleep feel less dreams. In addition, most of the dreams that people can remember are about to enter the awakening, and the dreams that have just fallen asleep have long disappeared without a trace, which is another reason why people feel that they have more or less dreams. < / p >
< p > Why do people dream, and how do they react if they don't dream? Scientists have done some experiments to stop people from dreaming. That is, when the sleeper appears the brain wave of dreaming, he is immediately awakened to prevent his dream from continuing, so repeatedly, it is found that the deprivation of dream will lead to a series of physiological abnormalities of the human body. such as blood pressure, pulse body temperature and skin electrical response capacity have an increasing trend, the function of the autonomic nervous system is weakened, but also cause a series of adverse psychological reactions Such as anxiety, irritability, perceptual hallucinations, memory disorders, disorientation and so on. < / p >
< p > it is obvious that normal dream activity is one of the important factors to ensure the normal vitality of the body. Because the activity of the right hemisphere is dominant in dreams, and the left hemisphere is dominant after awakening, in the course of 24-hour day and night activities of the body, awakening and dreams appear alternately, which can achieve the dynamic balance of neuroregulation and mental activity. Therefore, dreams are a way to coordinate the balance of the psychological world of the human body, especially for people's attention, emotion and cognitive activities. < / p >
< p > psychologists believe that there is great potential for human intelligence. In general, less than 1max 4 is used, and the other 3max 4 is hidden in the unconscious. Dreaming is a typical unconscious activity. Through dreaming, you can recombine existing knowledge, reasonably integrate new knowledge with old knowledge, and finally store it in a warehouse of 100 million, making knowledge your own wisdom and talent. Dreams can help you to think creatively. The rich achievements of many famous scientists and writers also benefit from the enlightenment of dreams. < / p >
< p > A survey of accomplished scholars at the University of Cambridge in the UK found that 70% of scholars thought their achievements had been inspired in their dreams. A similar survey of 60 mathematicians was conducted by the University of Geneva in Switzerland, and 51 admitted that many difficult questions had been answered in dreams. < / p >
< p > if people can't dream, it may lead to mental and personality disorders to some extent, and even affect the exertion of mental inspiration. Dreamless sleep is not only of poor quality; it is also a sign of brain damage or illness. Clinicians have found that some patients with headaches and dizziness often complain that they no longer dream or rarely dream during sleep. Diagnostic tests have confirmed that these patients have slight bleeding or tumors in their brains. < / p >
< p > Medical observation shows that the dream sleep of dementia children is significantly less than that of normal children of the same age, and the dream sleep of the elderly with chronic brain syndrome is significantly less than that of the normal elderly of the same age. 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 needed for the healthy development of the brain and the maintenance of normal thinking. If the brain regulatory center is damaged, there will be no dreams, or only some incomplete dream fragments, if there is no dream sleep for a long time, it is worth people's vigilance. < / p >
< p > of course, long-term nightmares are often a sign of weakness or some illness. < / p >
