Sleeping every night and dreaming all the time is medically known as excessive dreaming, which is one of the manifestations of sleep disorders. It can lead to poor sleep quality or even early awakening and difficulty in maintaining sleep. Patients often feel sleep deprivation, fatigue, a sense of tiredness or memory loss during the day, and the causes of excessive dreaming are mostly related to the patient’s psychological factors. If they occur in the short term, most of them are triggered by external events, such as excessive stress, mental tension, or the removal of the stressor after the external event has passed, the patient’s symptoms can gradually improve. If it exists for a long time, it is usually related to the patient’s mood disorder, such as anxiety disorder or depression, and the anxiety self-assessment scale and depression self-assessment scale can be improved to clarify the degree of anxiety and depression of the patient.
