Ghostly Car Ad
Be sure to turn up your volume so you can hear the reaction of the camera man as he was filing this footage.
This is a car advertisement from Great Britain. When they finished filming the ad, the film editor noticed something moving along the side of the car, like a ghostly white mist. They found out that a person had been killed a year earlier in that exact same spot. The ad was never put on TV because of the unexplained ghostly phenomenon.
