The questions of whether there is life after death and, if so, what it's like have puzzled humanity throughout history. Seeking reassurances from the great beyond, people have tried to make contact with those who have died in hope of gaining definitive proof of the afterlife or obtain other helpful knowledge. For centuries, people have attempted to forge bridges to other worlds through summoning the dead, dreams and visions, trance, mediumship, channeling, mirrors, gadgets, and other means. The history of spirit communications stretches from ancient times to the high-tech present and involves flamboyant personalities, genius inventors, spectacular failures and frauds, and equally spectacular alleged successes.Spirit Communications explores all of these modes of communication and, wherever possible, separates fiction from fact. The book discusses how spirit communications work and what communicators do, but cautions young readers against do-it-yourself spirit communications, such as entering into trances or using risky devices, since the practices can be dangerous for those who are unprepared.Chapters include:Dreams and Visions Ritual Trances and Altered StatesSéance SpiritsInterdimensional ToolsPsycho-What?
