This is when the main character finds himself/herself going up against a vengeful god/being or other supernatural force. A ghost comes to mind here.
Who hasn’t read a good ghost story or seen a spooky movie? This conflict deals with man versus something other worldly. Yes, that means ghosts/spirits. The Amityville Horror Movies are great examples. Do you like ghost stories? I do. To a point. I’d rather watch one that read one though.
