i am very surprised no one has mentioned "Saw" and "Saw II" that puppet made me stay awake for 5 days (atleast) dolls/puppets creap me out
The Saw films didn't really scare me but they did make me squeamish. Especially the start of the second one where your man has to get the key from behind his eyeball with a rusty scalpel. Every time the blade got close to his eye, I did a full body cringe.
