As a tribute to Rosemary Ellen Guiley, who recently passed away, we present this fascinating hour from October 2015, when she kicked off our yearly Ghost-to-Ghost show, with a discussion of black mirror scrying, and how this technique is used to contact the dead. Scrying means to gaze and to discern dimly, Guiley explained. "Black mirrors are used in dim light and they reveal things... the past, the future, the astral plane, the dead, the spirits, and amazing things can happen by gazing into a black mirror."
