I have only had trouble with losing it during dreaming. Whether this is demonic or not I can't give a 100% verdict on, but I used to have good luck sleeping with no internet around me. Something about the perceptive ability of the brain to receive signals even passively, while unconscious, has led to me having very disturbing dreams when surrounded by WiFi et al. Sleeping in the middle of nowhere has also helped, though it is more dangerous if someone unsavory or with ill intent were to stumble upon your camp. How have some of you who have mastered nofap gotten rid of the wet dreams?
Wet dreams aren't a problem in my opinion. It goes away until some time in the future. Likewise you aren't really sinning because it comes of its own accord. Let it pass.
