What was the scariest sceen in a horror movie?

[SykkBoy]

We've discussed favorite movies, scariest movies, etc. but what ONE scene was the biggest chiller for you?

For some reason the scene that gets me is in the Japanese version of The Eye

The "Who's in my chair?" scene
there's not even a music cue when this thing jumps out at you...and I'm usually not affected by things jumping out of nowhere...
