Ghost

2012-05-07 - night - I was jogging and know when I was looking down I saw a black figure. It was big and was like a rectangle with a triangle cut out with two triangles on the side sticking out at the top and bottom. For some reason, I have the illusion that the top and bottom are small, like 1 1|2 feet. It might have been 10 feet long and 5 feet wide. This startled me. It gave me the feeling of it like quickly bouncing from side to side. It was quite black. I really saw this.
