I am a man of science, so I'm not posting this because I think its an orb or some magical ethereal entity. Logic tells me bug, but was unaware they could move like that. Is it ball lightening? My camera caught this at 4:49AM.  Everyone is fast asleep. The light in the upper left that comes off and on is another camera mounted across the room which has flashing led lights. Don't be confused by the brightness of the bug or thing because it may just be reflecting the IR light from the camera and not necessarily producing its own light. I've captured other bugs that were about as bright in reflected IR light, but they flew like bugs. This one is either a really fast bug, or something else.
