By d. emerson eddy — One of my favorite things in horror is uncertainty. Horror often taps into one of the primal fears, fear of the unknown, fear of that unseen thing lurking on the threshold, but it can also often subvert it. You'll most often see it in the form of other characters disbelieving the weird and supernatural things that beset the protagonist, but sometimes the story goes beyond that. The way that the story is told you can be questioning everything that you see or are told by the author, by the characters, by the atmosphere of the tale. Particularly in a good psychodrama or surrealist horror, you're left wondering if anything is real, something like Carnival of Souls, The Lighthouse, or Jacob's Ladder.
