ghost caught in the camera

This video is a CCTV footage which was recorded in night in a hospital or mortuary. In the video, one can clearly see a corpse is lying on a couch covered with a white sheet. As time goes there appears something spooky from the body like white smoke, on close attention it looks like a spirit / ghost is raising from the corpse which then flies outside the hall in a high speed...... may be something escaping from the body after death.....interesting right ?!!
