Dreams are a subconscious expression of emotions, and everyone dreams. However, a strange phenomenon occurs during male sleep, namely dream ejaculation, clinically known as dream ejaculation, which is a kind of seminal emission. If it is an adult, occasional not frequent ejaculation is a normal male physiological phenomenon, so is dream ejaculation. But if long-term dream ejaculation is easy to cause psychological burden, need to adjust in time. The causes of dream loss can be divided into two main parts, physiological and pathological dream loss. This is physiological dream loss, which is caused by excessive semen storage in the genitalia and occurs mostly in young adults. In addition to the stimulation of sexual organs or urinary system diseases, the main reasons are mental and physical factors, such as excessive mental tension due to long-term thinking about sex-related problems, excessive physical fatigue, and excessive sexual stimulation. Generally, the frequency of dream ejaculation in adult men is once a week or occasionally two or three times a week, which is normal, but if the frequency is too high for a long time, it will not only affect sleep but also cause harm to the body. To overcome dream ejaculation, first of all, we must understand and master the correct sexual knowledge, develop a good sexual psychology, and avoid excessive sexual stimulation; secondly, underwear should not be too tight, sleep under the blanket temperature is not too high, and strengthen physical exercise; finally, to maintain a good state of mind, do not have a sense of guilt and guilt, learn to self-direction. If you still have long term seminal emission, you should go to the hospital for examination and treatment if necessary. Therefore, infrequent seminal emission is a normal male physiological phenomenon, and so is dream emission. However, if long-term wet dream is easy to cause psychological burden, it needs to be treated in time.
