The Time Slenderman Visited My House

Once, it was foggy. Like, really foggy. I heard a knock at the door. I was taught not to let strangers in. So I didn't open the door. I heard the knock again. And I heard in my mind: "If thou dost not open the door, I will kill thou and everyone thou knowest." I looked out the window. It was a man. Except it wasn't a man. He wore a tuxedo, but had no face. Suddenly, I moved toward the door without making myself do it. I proceeded to open the door. Then I woke up.
