The Horror Challenge,
A frightening dream sequence/hallucination.
That moment in Freddy vs. Jason where the girls on the swing are singing that song: One, two, Freddy's coming for you. Three, four, better lock your door. Five, six, grab your crucifix. Seven, eight, gonna stay up late. Nine, ten, never sleep again. Oh man, those girls are giving me the creeps. I believe it's also from a original Nightmare on Elmstreet, but I can't say for sure, so correct me if I'm wrong.
