Ghost Lights Picture

This ghost picture was taken in a haunted house at night, when the camera was set to take pictures automatically.  The red glow is from an exit sign, but the white lights are unexplainable, even after analysis.  The haunted house has accounts of an apparition of an old lady appearing to construction workers; lights turning on and off; footsteps up and down the stairs; and objects stacked in front of doors to block the workers from disturbing a room.  Some of the construction workers were so afraid, they wouldn't work without a radio playing loudly and the front door open.
