Nightmares!?

Im 14 years old and a few weeks ago saw a scooby-doo espisode with a scary mummy. It was pretty intense....i haven't benn able to get to sleep since i saw the movie. Im afraid that my nightmares won't go away....what will get my mind off of this voilent horror??? p.s. if you don't like horror don't watch scooby doo. and please take this seriously... my friends have been making fun of me but it is true!!
