The Ultimate Vampire Resource and Directory

Describe a movie as badly (and accurately) as possible. The next person guesses the movie, then posts a new badly explained plot.

Example:
"A man refuses to leave a castle and everyone who visits keeps losing blood." (Dracula)

Please use Google if you're stuck instead of wild guessing.

I'll start:
A group of teenagers keeps getting told not to fall asleep, and they keep falling asleep.

Some dude's chilling, and a mystical grandpa rolls up. Together with someone else and a walking carpet, they learn space magic. They go rescue a lady, and then blow up everything up.
