I stopped going around 17, and I still looked under my bed half way thru twenties. And still, whenever my gf goes away for the weekend to visit her mother, I feel at unease, being alone in the appartment. I really hate being that way, that I have this anxiety still, it`s embarassing (to myself). That shit is always going to be with me, I now realize. But here`s a trick that might help a bit: When you`re lying there in bed, and you start feeling at unease, and you know that pretty soon you`re going to have to turn around (you know, to look for that demon that might be hiding behind you, lol), or you have to open your eyes to see if there are any demunz in the room, try to think about something else. Let your mind wander, daydream, travel in your mind to a safe place that you love, but just don`t think about those demons. And before you know it, you`ve fallen asleep (and then the demon`s gonna get you, lol ).
The demon-crap is probably what I hate most about my upbringing, and my parents, mainly my mother, she was literally obsessed with demons. Parents are supposed to calm down their kids when they reach a certain age, and start thinking about ghosts and stuff like that, but JWs do the exact opposite: They feed the childs fear! "No kid, there`s no such thing as ghosts, that`s just silly superstition, but there is something much, much worse, there are demons"! What the fuck is that crap!?!?! (btw, I think Garybuss is wrong this time, there`s nothing wrong with you, this demon-anxiety is very common among JW-kids, especially for those that had parents that were very focused on it. It will often take years to get better).
