I'm not sure it means that....if you look at tv shows like supernatural...well someone has to write it.....maybe you have a talent for dark stories
If its all just fictional then its dark fiction, if it was really how you thought and your preception of the world then that would be a definate yes.
No i don't think so. Writing is only a form of ex<x>pression no matter what you write about! Besides look at all the talented writers out there you just may turn out to be one.
