What freaked you out as a kid?

The storm in The Wizard of Oz. I don't remember but I used to be scared of wind for a few years, probably until I was like 6 or something.

As a teenager, John Carpenter's the Thing and the second (70's) version of the Invasion of the Body Snatchers both gave me nightmares.

I also loved the TNG and B5 alien 'replacement' episodes.
