I find nd vintage fairground stuff, like the horses on the carousels frightening for some reason, and very old dolls. Maybe the style of the painted faces perhaps?
I used to be terrified of the cybermen on Dr Who, again possibly because of the blank expression on the faces.
The thing that most creeped me out though was when I was in the Rangers (post Girl Guides) was going to our meeting place, which was a small room deep in the depths of the churchyard, and being terrified of having to go past all the graves in the dark. I used to take a torch but was frightened to use it, in case it showed up anything creepy or grisly looming at me out of the dark!
Nowadays it's slugs which creep me out, horrible things.
