Does human consciousness survive death? Can it manifest itself to the living? And can science study alleged paranormal phenomena? In Apparitions, Hauntings and Poltergeists, Dr Robert Young provides an accessible and informative introduction to the science of Parapsychology, drawing on years of study and first-hand experience as an investigator of paranormal phenomena. This book makes public the case files of The British Ghost Society, an organisation founded and led by Dr Young which has conducted investigations at many of Britain's allegedly haunted buildings, with dramatic and thought-provoking results. Alongside case studies of classic cases of haunting, apparitions and poltergeist phenomena, Dr Young reveals the true stories behind famous ghost movies, from The Exorcist to The Conjuring, and asks: are paranormal phenomena really evidence of disembodied souls, or are they manifestations of as yet unexplained powers of the human mind itself?
