I really don't know how to explain this video I just downloaded. Here's the copy from the site I found it on. When you see it, tell me what you think it might be, because I'm stumped:

"This is is a car advertisement from Germany . When they finished filming the ad, the people who made it, noticed something moving along the side of the car, like a ghostly white mist.

If you turn up the sound, you can also hear whispering. The ad was never put on TV because the unexplained ghostly phenomenon frightened the production team out of their wits. Watch it and about halfway through (after the car comes from behind the trees) look closely and you will see the white mist coming up from behind the car and then following it along the road!"
