Mothman

You walk about in the forest by your house. You have a routine of doing this every night. Tonight, the woods is rather misty, and a bit chilly. You see a figure in the trees above. It's hard to see them, but it looks...odd. You try to ignore it, assuming it's an owl or something. However, after a few minutes, you hear something land on the ground behind you, as if diving or...flying.
