I have always felt a little bit uncomfortable with question [why I'm write these stories]. It's not a question that you would ask a guy that writes detective stories or the guy that writes mystery stories, or westerns, or whatever. But it is asked of the writer of horror stories because it seems that there is something nasty about our love for horror stories, or boogies, ghosts and goblins, demons and devils.
Stephen KingThere's a Mr. Hyde for every happy Jekyll face, a dark face on the other side of the mirror. The brain behind that face never heard of razors, prayers, or the logic of the universe. You turn the mirror sideways and see your face reflected with a sinister left-hand twist, half mad and half sane.
