I can't sleep -read-?

Here's the deal, I just watched Pride and GLory with my boyfriend, it was his turn to choose the movie, so that's what he chose, I have no problem with that type of movie, but considering we watched it in total dark, and now I'm trying to sleep, and I just can't fall asleep, basically all the gory scenes of the movie are playing in my head, and I can't fall alseep of it, now, I'm not scared or anything, but I need to get up early tomorrow and what not, ideas on how to get these out of my head and going to sleep
