1. is a trick of image. The video is a fake.
2. It is a reflection in the glass of the camera lens itself.
3. The video is genuine and, indeed - is a registry of a disembodied spirit of a man, probally, the man who died in the accident.
Many people who commented this video, the question or doubt about its veracity argue that the "ghost" is dressed and that it seems (to them) obvious that "souls" desincarnated should not use not clothes because clothes are material artifacts that don't make part of a soul.
However, these people do not know that, according the theory of the Spiritist Doctrine, immediatily after leaving the body, especially in unexpected circumstances, the spirits still maintaining their physical appearance, including clothes because they still believe, they think - still be incarnates. In Spiritual Dimension of the Existence, ALL APPEARANCES are reflecting - objectively - the thoughts of the Spirit.
