I agree with what the others already said, I just want to mention that I really liked the fact that the main char doesn't act as stupid as other characters in horror movies tend to do.
Sure, she was maybe a bit to trusting in the beginning, but when she realized she was in danger she didn't hesitate to do what ever was nescessary to save herself!
That's the kind of behavior and common sense I miss in other modern scary stories. Well done, I enjoyed this fine little creepypasta.
