| I heard a theory concerning spirits a few years ago. The human brain, when under stress, and in conjunction with our memories and eyes, project images instead of taking them in. Sort of like turning a camera into a projector. This produces "ghosts". They may be memories of scenes in our past, or from dreams, or even from television or films we have seen in the past, perhaps even books we have read. Don't know if I believe it, but it is food for thought. |
