Yesterday I stumbled on a story site. And it has over 1000 stories in it's Horror/Scarry section alone. Well it is a mix of stories/interactive stories/poems/images and even some surveys.
I found a few good stories that seem to go with Little Fears, though you might need to do a little sifting. And in one of the surveys the question is asked what kind of monster did you have as a kid, closet, underthebed, in the basement and along that line.
If you have the time, check this site out and if you have the extra time, post some of your own stories there.

If you do happen to post any stories, it would be a cool idea to add a link to the little fears site if possible.
Just a thought
