Movies/books that scared the "bejeebers" out of you.

[fascination]

I don't equate blood and gore with scary. Gore is cheap and gross, not scary. For true scary movies, I liked:
"Signs" starring Mel Gibson. Written and directed by M. Night Shymalan. It was funny, sad, charming, touching, and SCARY as heck. Schmaltzy ending, but I'm OK with that.
"The Changling" with George C. Scott and Trish Van Devere, 1980. No gore, no guts, no blood. I saw it at the theater in 1980, and I'm still scared. I don't think it has ever been shown on television. For a long time, it wasn't available for rental or purchase, but I think it is out on DVD now.
