One of the most interesting short stories I've read recently is "The Body Politic" by Clive Barker. It can be found in the Books of Blood Volumes 4-6. For anyone that doesn't know, the Books of Blood are a collection of short horror stories.
Summary:
Charlie George sees himself as a normal person, nothing less and nothing more. But hidden from him, are the thoughts of his hands. Every night, while Charlie sleeps, they plan their escape. One night, Charlie awakes from his pleasant dream to find himself killing his wife. His hands, now in control of themselves, seek to remove themselves from him. Right, the leader, chops off Left to spread the message to hands all over town of life after separation. This revolution ends with the death of Charlie George and his Right hand. The story, however, ends on a rather uneasy note, the thought of another uprising of any part of the body.
Review:
One of the reasons I enjoyed reading this story is because it frightened me. Usually when reading short horror stories (by other authors), I've found that they're mostly weird (though still enjoyable), not really horrific. In contrast to those stories, Clive's can conjure up horrific images and situations. One of those stories is "The Body Politic." The thought of your hands (or any other part of your body) controlling itself is terrifying. And the thought that they would want to separate themselves to live a life of their own is even worse. One of the descriptions that I found really disturbing is the comparison of a severed bloodied hand to a red spider crawling around on the ground. I think this description has stayed in my mind, because a giant spider is scary enough on its own, but when you know it's actually a severed hand covered in blood and moving around, it just makes it even more terrifying.
