Scariest film moment?

[Deckard]

@Myrrh: Yeah, some of those Japanese (and, more generally, Asian) horrors are really quite disturbing - the Eye, the Ring, Audition, etc.

Separately, can anyone tell me what film had a trail of zombies or vampires (can't quite remember which) just horrifically "floating up" to someone's bedroom window at night and scratching to be let in? I saw it a long time ago on TV. Damn that disturbed me! Put me off ever opening my bedroom curtains at night in case there was a face staring in at me!
