I'm wondering if anyone has any good short horror stories. Like 3 or 4 sentences long? I have one but I can't remember if it's unintentionally plagiarised or not: You know when you see something, just for a second, in the corner of your eye. Something that should definitely not be there but you dismiss it as a delusion, the limits of your field of vision, your eyes playing tricks. What if for that split second, what you really saw was a break in the veil of reality. And what if, in that split second, something slipped through.
