[/INST] Hello, Nightfall or nocturnal ejaculation is normal and it happens because of the accumulated semen inside your body. Nightfall is common when you do not masturbate. Do not worry. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr K. V. Anand, Psychologist </s>
