What makes the scariest 2 - sentence horror stories so effective?

The element of the unknown. In horror scariest stories, often what we don't see or understand is the most frightening. For example, in 'The Blair Witch Project', the idea that there is some unseen, malevolent force in the woods creates a sense of dread.
