Apparitions represent a rich collection of phenomena. They have been seen personifying the forms of the living and of the dead, at the exact time of the agent's death and often a considerable time after. This essay, chapter 16 of Psyhic Exploration, explores apparitions, haunting, and poltergeists. The full volume of Psychic Exploration can be purchased as an ebook or paperback version from all major online retailers and at cosimobooks.com.
