Explore the mysteries of immortal souls, restless spirits, and echoes from beyond the grave in this in-depth study of ghosts in all their guises. From the earliest recorded beliefs about the afterlife to today's Hollywood ghost stories and Halloween festivals around the globe, learn about the faiths, practices, and rituals that surround this most enduring of myths. Examining other unexplained phenomena including out-of-body experiences, reincarnation, and soul mates - lovers who find each other lifetime after lifetime - this book investigates both the scientific and the mystical reasoning behind ghosts' unfinished business. With analysis of the methods used throughout history to view, record, and contact the dead, along with the modern-day equipment and defences used in the field, Ghosts also provides you with all you need to know to plan, conduct, and publish your own paranormal investigation. Discover how ghosts present believers and sceptics alike with one of life's greatest challenges, and a riddle that the world cannot yet explain.
