It came to me in a dream

We all think we're average or normal, I mean we fight to be normal. What is so good about being normal. I always thought I was semi normal, I mean My name is Scarlet, anti-social to the max, I dye my hair to often and I don't like people. Pretty normal or basic as we teens would call me. What happens when the dude in my dreams start talking to me; and I don't mean your average conversation of hellos and goodbyes but, when he starts talking to me and telling me things that haven't happened and he's the one doing the killings. How do you stop him? You can't go to the police, He knows to much and I know he has no remorse. Plus the police would just think you're crazy or you're the one at fault. You can barely remember what is face looks like because,
dreams are wack and there suppose to only be dreams, right? Or am I actually crazy?
