Dreaming may be a physiological phenomenon caused by environmental, psychological, physical and somatic factors. As long as it does not affect the daytime life, it is normal, but if it affects the working life, it needs to be taken seriously. The main reasons for dreaming every night are as follows: somatic factors: the stimulation of various environmental factors outside the body during sleep, such as light, temperature, sound, odor, sleep environment changes, etc., will be brought into the dream; some discomfort in human waking hours will be brought into the dream, such as neurological diseases will often dream of being hit on the head, auditory center lesions will appear strange sounds in the dream, respiratory system diseases For example, neurological disorders often lead to dreams of being hit on the head, auditory lesions often lead to strange sounds in dreams, and respiratory disorders often lead to dreams of poor breathing. Psychological factors: It is often said that “there are thoughts in the day and dreams in the night”, if you are always thinking about something during the day, this thing will also recur during sleep; scientists have found that dreams often reproduce the daytime experience. Almost all dreams are related to people’s daily work, wishes, imagination, memories, worries, thoughts, worries and other mental activities. Excessive psychological burden can also lead to excessive dreaming, such as a tense mind before bedtime, worrying about symptoms of excessive dreaming, etc.; physiological factors: too full or too hungry before bedtime, daily smoking or heavy drinking, drinking coffee, tea or functional drinks, strenuous exercise before bedtime leading to mental exhilaration, too much sleep during the day; and reading books too long before bedtime. Therefore, good sleep plays a supportive role in human health, and if long-term excessive dreaming affects the quality of sleep needs to be adjusted in a timely manner.
