I think the story about the person who kept seeing a figure in the corner of their eye, but when they turned, there was nothing there. This plays on our paranoia and the fear of something being there that we can't see or understand. It makes you constantly on edge, always looking over your shoulder. And the fact that it happened repeatedly to the person in the story just adds to the horror.
Personally, I find the story where a group of friends went camping and strange things started to happen in the woods at night to be the most horrifying. They heard growls, saw strange lights, and one of them even felt like they were being watched. The isolation of the woods, combined with the unknown source of these events, is really terrifying. It gives you the feeling that you're at the mercy of something you don't know.
