I would say that the dreams are showing you're getting waaaaaay into the horror movies too much lol. You're REALLY experiencing them as you watch them I guess, and you can really picture yourself in the situation with zombies. I love horror movies, but I'm able to separate myself from the movies and the scary aspects. I would have said you have a phobia too, but you just keep watching them :P unless someone is forcing you to watch it with them. haha. well, those dreams i figure are just showing whats really on your mind lately. I like to think of dreams as our subconscious' method of expression, consolidation, reorganization, and communication. At the same time, it could really mean nothing :P.
