Every kid has their "I'm creeped out" threshold - here's some of the things that I recall terrifying me as a kid ....
(Bear Country Jamboree)
Open closet door at night
Mall Santas
Clowns
Old lady houses filled with figurines and the smell of lavender and moth balls
Dentist's office chair
Cluttered attics
Unfinished basements
Hospital corridors
Baby dolls
The child catcher from "Chitty Chitty Bang Bang"
Wicked witch and flying monkeys from "Wizard of Oz"
