What was the scariest sceen in a horror movie?

[Rochard]

I don't get scared by movies as a rule.

But I had never seen Jurasic Park and caught it on TV one night when I was alone. I had turned out all of the lights, and was laying down on the floor (big fat shag carpet!) on my stomach with my feet up on the couch behind me. I had my head propped up with my hands. Some shit jumped out, scared the piss out of me, and boy, did I ever move!

The following day I still had nasty rug burns!
