If there's one part of a supernatural movie that everyone can confess to being just a little bit freaked out by, it's ghosts. Unlike their closest cinematic companions, zombies and vampires, you're roughly a gazillion times more likely to encounter a spooky resident in your home that a blood-sucker or flesh-eater.
