In general, talking in your sleep every night is not a disease, but a normal physiological phenomenon, and some people are just prone to talk in their sleep. However, there are some cases, especially when the dream talk is more frequent and occurs frequently, it may be caused by some diseases. If the patient has high mental stress, poor sleep quality, reading horror books, thriller movies, etc., it is easy to have the symptom of dream talking every night, often caused by overexcitation of some brain nerve cells, at this time the patient needs to avoid the trigger, so as to alleviate the symptoms of dream talking. If the patient is a child, he or she is also prone to dream-talking every night due to unstable and incomplete neurological development. As the neurological system becomes more stable and sound with age, the nightly sleep talking will gradually decrease. If there are no other uncomfortable symptoms, there is usually no need to worry too much. However, if the patient is accompanied by recurrent awakening, strong anxiety and other uncomfortable symptoms, it is necessary to consider some disease factors, such as night terrors, obstructive sleep apnea syndrome, anxiety disorders, depression, etc. At this time, the patient needs to go to the hospital for polysomnography, EEG and other related examinations to clarify the specific cause and then carry out targeted treatment.
