Nah, that's perfectly normal. You need to get out your psychotic tendencies somehow.
I once wrote a short story about a cannibal in excruciating detail, right down to him talking about the texture of his meal's meat :/
Also, nothing wrong with being slightly insane. It just makes you more creative than everyone else /o/
Baa baa black sheep have you any booze? No sir, no sir, I'm a....sheep~
