What a great shot! The light certainly does tweak the imagination, but,like you,I'd like to believe that the "apparition" in the mirror is the ghost of Bodie past. The whole place seems to be inhabited by ghosts of the past.....why not this mirror?
A very special image -- the apparition in the mirror can be ready by the imagination in a number of ways. A ghost, the ravages of time, or a look into the past.
