Ghost of the Living and Ghost of the Dead

Once upon a time, I saw three ghost figures in the tall ceiling on a cold dark night in October. They were talking to each other and appeared to be very happy to see each other I was glad to see ghosts of the dead, as they are still there in secondary form. Ghosts in the top of the ceiling during the Aurora Borealis are ghosts not yet born. Are these Borealis people?
