Scariest dream i have ever had?

Well, it could be that you just watched a scary movie around the time of the dream. It could also be your subconscious trying to tell you something, or that paranormal crap you don't believe in. I like to think of dreams as free movies when I sleep, and yours is definitely one that sounds interesting. I say don't worry about it and just think of it as entertainment. If there really is a purpose for this dream, it will show itself in due time.
