Does your writing scare you??

I recently entered a contest on writing.com that has me a tad bit worried. I begin to wonder if Stephen King ever re-read his own work and thought to himself "Dang! I am one twisted F%ck!"
Have you ever written anything that has scared you? Something that has made you wonder what dark recesses of your mind came up with that story? Have you ever written something that has made you wonder if you need deep psychological help?
I would love to hear that I'm not the only one out there that is disturbed by what comes out of them when writing.
