I’d like to share with you a couple of things that scared the holy whatsit out of me as a kid, if I may. I was reminded of the first one by your recent post about Super Naturals – here in the U.K. we had a Super Naturals comic, and there was a separate strip in it about an evil ventriloquist doll, just called, I think, “The Doll.”
If I remember correctly, a young boy goes to live with foster parents, and discovers the ugly doll in his bedroom. I think it belonged to the foster carers’ dead son, and the dad goes mental and chucks the doll in the bin, and the image that always stays with me is how the doll scratches him as he throws it away…brrr!
The other thing that had a deeply unpleasant effect on me as a kid was Disney’s THE WATCHER IN THE WOODS. I only managed to gather up the balls to watch the full film a few years ago, and discovered it to be a weird sci-fi thing, but the idea/image that always bothered me was the parts of the film which used the POV of some invisible force watching people…in the woods!
I couldn’t go in or near wooded areas for YEARS; I even had to avoid large front gardens with a lot of trees in them, because I was certain the “Watcher” was in there, being all creepy.
