Still Scared

Just a warning. Yes I've been sick, and that guarantees me nap time almost everyday. Lucky for me I have the time or I'd never get healthy.
Today during my nap I had that dream, AgAiN! Some people have heard this story before but here goes.
About a week ago I decided that I wanted to try out the Red Box, and instantly got addicted. So I rented again, I became a movie buff overnight-there was no stopping me. I rented Strangers
Normally Horror movies Do Not affect me in the slightest bit, but this one did. The entire movie prompted 2 dreams exactly alike within a few days. Now I don't know much about dreams, but if someone does and wants to let me know what the diagnosis of my dream is, feel free.
I dreamt me and a friend were the two main characters. To the tee!!
We were scared shit less, and I felt like I was living the movie. Those masked people are something else.
I want to know why I had that dream yet again just an hour or so ago, there is something wrong with me. Overactive imagination or something.
That movie freaks me out, literally.
I don't recommend it, to anyone. Just for the fear factor, by god I watched way worse than this....but there is just something about the killers in this particular one that really gets me.
An incredibly thrilling imagination is what I have, turn if off. Please?
