The Ghosts of Borley

Apparitions is most influential in categorizing ghosts. These four categories include experiments, crisis, post-mortem and ghosts. Tyrrell's classification of phantoms is an interesting and thought provoking one, his system is been continued in its use today, demonstrating that he was ahead of his time. Tyrrell develops the idea that the apparition may be a way for the unconscious part of the mind to bring to consciousness information that has been paranormally acquired? In crisis cases, for example, he introduces an evocative metaphor of a mental 'stage-carpenter', behind the scenes in the unconscious part of the mind, and constructing the quasi-perceptual experience that eventually appears on the stage of consciousness, so that it embodies paranormal information in a symbolic way. Tyrell first introduced the term out-of-body-experience in this book.
