So I just got done watching the horror movie "Insidious" and yes I know some will say horror movies are a sin but they dont have a bad effect on me personally I realize its just entertainment. Anyways in the movie there was a lot of "ghost" apparitions and things moving on its own and even one slapping a girl lol, but one of the exorcist ladys said it was a evil demon haunting them and I was thinking do demons mislead people into thinking when you die you stay on the earth and you just walk around haunting places?
