Just find some inspiration and write something, even if you just post it in the Writer's Workshop. Talk to friends, ask them what some of the scariest things are that they've encountered in their lives, and work from there.

Or, as suggested below, just read through some of the work here and see if any of it moves you. Most of all though, don't try and rush inspiration. Wait until you feel really strongly about a concept, and then refine the hell out of it until you think what you've got is a good story.
