The blue 'ghost' could be one a piece of 'fluff' from those towels to clean your windshield, LOL...........if it was REALLY close up to the camera fluttering around I think THAT is what it would look like.
Now the one that Yoko posted was more 'creepy' like shaz said............the looks of it mixed with the info of some of those cars coming in THAT DAY from a fatal crash............:yikes:
