I was raised in the JWs. I could go on and on about what constitutes praying to, allowing, signs, etc. about the demons. You could get demons if you bought something from the second hand store that looked "too old." You could get demons from associating with a person at work that did the tarot. You could "get demons" if you did yoga. Almost every circumstance from normal life you could get demons, depending on who was interpreting it.
I have been a ghost hunter for several years. I am a skeptical ghost hunter. I say that 90% of my investigations are just some normal explanations. In all my years as a ghost hunter, I have never encountered what I would consider a DEMON. Never. I've had things move in my presence, I've had voices on tape, but nothing so scary as a demon might be. My Mother thinks I am demon possessed because I'm a ghost hunter, and am SEARCHING for paranormal activity, that Satan must have planted himself on my doorstep and I have demons.
I have always know that DEMONS are mischevious tricksters, at least that is what I thought. But, even in the most malevolent of investigations, there was no demon coming at me with claws, fire breath, all that. I've always encountered just harmless entities.
Demons.. PFFFAH!
