Thanks to Daniel for sharing this video clip
This video was captured during a karaoke session at home. One of the friend was suppose to be on the way to meet up with them but he died in an accident. Obviously, the ghost appears in this clip was him. This video was taken on the same day when this group of friends was waiting for his arrival. They were told of the accident by police when they were trying to get hold of him in his mobile. They played back the recorded video few days later and notice the spirit of their friends indeed was there sitting behind one of them. They were of course horrified.
