Certified Hypnotherapist, author and lecturer, Yvonne has helped many victims of post traumatic stress work through their anxiety. She notes that many subjects, during their regressive hypnotherapy sessions, describe alien abduction trauma. Lecturing extensively at M.I.T. and other universities and at many American and international UFO conferences, Yvonne frequently lecture-toured with colleagues Dr. David Jacobs and the late Dr. John Mack and Budd Hopkins. In this presentation, Yvonne will be discussing her case studies single abductions, cases of double abductions as cited in her first book, Chosen-Recollections of UFO Abductions Through Hypnotherapy and cases of multiple of mass abductions she is currently writing about in her new book about the Coronado Island incident.
