A detailed academic and popular investigation based on 400 mostly unpublished accounts of spiritual and religious experiences of unusual lights. This book explores the fascinating possibility that they may present us with evidence of 'other worlds' alongside our own.

This book is a study of unusual light phenomena, based on almost 400 unpublished accounts of modern-day encounters with strange lights collected over a period of thirty years, held at the University of Wales, Lampeter. It is an original and perennially topical book that goes beyond existing studies of unusual light phenomena - such as lights encountered during angelic experiences, near-death experiences, 'after death communications' - in a number of ways. It shows, for example, that experiences of unusual, spiritual, religious and paranormal lights are cross-cultural, trans-historical, and are reported widely in the present day: but not necessarily experienced when near to death. It also demonstrates that these experiences share to a remarkable degree a 'common core', showing by drawing on a large number of vivid, unpublished and dramatic testimonies that unusual lights typically manifest at times of crisis, and are overwhelmingly benign and loving, producing 'turning-points' in the lives of experients and typically setting them in new spiritual and creative directions.
