Enuresis refers to the spontaneous release of semen without sexual intercourse, which is different from physiological and pathological. Traditional Chinese medicine refers to the phenomenon of nocturnal emission as nocturnal emission or spermatorrhea. Those who have dreams but leave behind are called "wet dream", those who have no dreams but leave behind are called "nocturnal emission", and those who even slip out of semen when awake are called "nocturnal emission". Most of them are due to kidney deficiency, unstable essence, or disharmony between heart and kidney, or damp-heat betting. Western medicine is found in phimosis, redundant prepuce, urethritis and prostate diseases. What dreams leave behind is often the initial stage of waking up and refining.
