When I was a kid the things that really scared me were in those documentary style programmes about ghosts and all that paranormal stuff, where there were proper grown-ups (I thought) talking like scientists (I thought) about evidence (I thought) of paranormal things. They were grown-ups on Television, why would they lie to me or be that stupid?
I was never scared by things that I understood to be fiction. Like Night of the Living Dead (I loved that when I was little) or all that vampire stuff.
BTW: I was out shopping for four hours and when I came back you had produced about 100 pages of posts. That's utterly insane.
