Well, It was after dark, I was sitting on my bed playing, and I looked up at my window and there was a face looking back at me with a grotesque grin on it. I screamed really loud, and my parents came running to my room. I thought my brother had played some kind of prank on me with a mask or something, but he was in his own room.

The window was about 10 feet off the ground, so whatever it was that was looking at me was either very tall, could float, or was able to quickly set up a ladder and remove it.
