From the back cover: An experiencer of OBEs herself, Samantha Lee Treasure has dedicated over a decade to better understanding these extraordinary events. This illuminating guide is the culmination of this research, taking a holistic approach which draws together neurology, psychology, anthropology, parapsychology and religion. Her research has taken her from interviewing Korean and Siberian shamans, to participation in neuroscience experiments, fieldwork with the religious movement Eckankar, a year interviewing alien contactees and attendance at various workshops and retreats marketed within the growing spiritual marketplace. Based on experiencer interviews the author has conducted since 2015, the book will also explore how astral projection changes over the course of an episode or lifetime, taking into consideration generational, cultural, and biological differences.
