Dream talk is a kind of sleep disorder in which one speaks or makes some kind of speech other than snoring during sleep and cannot recall it after waking up. Modern medicine believes that it is related to mental factors, often combined with nightmares, sleepwalking situations, etc. It is mostly seen in children with neurological disorders and those with unstable neurological functions. Many people in life have the experience of talking in their sleep occasionally, and generally do not need to worry too much. The brain is composed of tens of billions of nerve cells, which have different divisions of labor. When people sleep, the brain rests, but a certain part of the nerve cells may not rest, because the nerve cells are still active, so people will dream, and the part of the nerve cells responsible for speech will command people to speak if they are still in a state of excitement, and this is dream talk. There are many reasons for sleep talking; children with incomplete neurological development and unstable neurological function may experience strong mental stimulation or overexcitement during the day, and sleep talking may occur at night, while adults may be induced by excessive stress and mental tension. Therefore, people who often talk in their sleep must strengthen their exercise, and at the same time pay more attention to rest, adjust the pressure brought about by work and life; often talk in their sleep may be a manifestation of neurasthenia, just need to adjust their rhythm of life, relieve the pressure, conditioning nutrition, appropriate increase some exercise, the problem will slowly get better. Many people will occasionally have the experience of talking in their sleep, which does not need to worry, but if the number of sleep talking is too frequent, resulting in fatigue during the day, depression, the need for appropriate treatment, the most important thing is to learn to relax in daily life, adjust the mental stress, which will help improve the quality of sleep and reduce sleep talking.
