I need help, and some answers please....

Ok, so, maybe I've just been reading way to many creepypastas, but lately I've been paranoid that one of the creepypastas has been watching me. I don't know why. Hell, I don't even know if they are real. Can someone please help me and tell me if they are real? And if they are real, how do you know if they are following/watching you? Thank you in advanced. I would research some pastas further, but If they are watching me, I dont want to put myself into any more danger than necessary....
