Twice, I've been woken up in the middle of the night...
And it's so dark all i've seen is a dark figure leaning over me. Not sure if it was just a really bad dream or what, But i've woken up to something talking. Which just made me scream and hide under my pillow.
And that gross feeling when your home alone, and you look down a long and dark hall way and you just get that sick feeling like someone's watchin' you.
