When we were kids we used to mess around with Ouija boards and one of my friends had tapes made by a priest that crusaded against the occult messages in Rock 'n Roll, which ironically got us more interested in the occult rather than less.
I remember us playing records backwards and scaring ourselves shitless, eating apples in front of mirrors and so on.
Whether that was just silly child's play or real danger I don't know, but I wouldn't mess with stuff like that now.
Also as a supposed rational lapsed Catholic, you couldn't pay me to spend a night in a 'haunted' house, despite the fact that I rationally don't believe in that stuff.
On the other hand, I can say that when I was a kid I had some childhood trauma to process and it may have taken the form of nightmares[1] and fear of supernatural entities. This could also explain my fascination with the topic back then---as a roundabout way of dealing with difficult emotions.
Anyway, if ignorance is a defence, what made you 'eat of the fruit of knowledge' so to speak?
[1] It also didn't help that my room was in the basement and so far from 'help' that I was totally on my own.
