The only horror movies I recall seeing are:
Invasion of the Body Snatchers (1980's remake)
The ending was so freaky! I almost wasn't able to get to sleep after this one.
Night of the living Dead (Bits of the original and the remake)
These didn't really scare me, and the old one was incredibly cheesy.
The Others
Not as scary as I thought it would be, but some parts did make me jump.
Return of the Living Dead (parts of it)
This one didn't even scare me a little bit.
The Ring
I LOVED this one. I'm seriously considering importing the originals someday.
Nightmare on Elm Street (Most of it, edited for TV version)
I saw this when I was about 10 or 11, (WITHOUT my parent's permission, of course
) This movie scared me so bad I was scared to death of taking a bath.
