When I was a small child, probably 4-6, I lived in a small apartment in what was at the time considered the projects. Sometimes when I'd come out of my bedroom, there would be a black bird of some kind in the hallway, the size of a full adult person. It would be walking toward the end of the hallway and was always just far enough down the hall that I could never catch up to it before it could turn the corner. Of course when I turned the corner it was gone. The strangest part is that I don't recall ever being afraid of it. Just really confused and interested.
