I'm sorry to say that the demon thing has been used on me in the past to very great effect. I had a very active imagination and several associates or family members with firsthand demon stories and it used to scare the living daylights out of me. I would sometimes spend hours in prayer at night, frightened out of my wits that things would start floating around the room, or that I'd hear voices or see eyes glowing in my closet, or be anally raped by a demon, or be held down in my bed and unable to move my arms and legs. These kinds of stories, from the platform, and from my friends and family, would often serve to reel me back in when I was experiencing doubt.
Ugh I'm getting all creeped out just thinking about it.
