Creepy stories

Who's There?

A few years ago, I was home alone at night time. I was watching tv in the living room when I heard the doorbell ring. Whenever I hear the doorbell ring, especially, when I’m home alone I am cautious to answer it. I walk up to the peephole without turning on the porch light (so they don’t know if anyone is actually home or not) and look through. It’s really dark but I can see a small figure (more like, black blob, idk it’s definite shape and had to be around 3-4 feet) doing like a dancing motion. Dipping down and oscillating its “arms” outward. Think of a person moving their arms like wings gracefully. It was dark outside but this figure was more opaque so I could see this going on. After a few seconds I stopped looking through the peephole because it was too freaky to look at. I regained some courage and looked back through and whatever it was was gone. To this day I still don’t know what that was and I get freaked out thinking about it.
