Is there any evidence to suggest that humans are being abducted by aliens?

Barbara Lamb and Nadine Lalich believe this to be true in light of their clinical research involving persons who claim to have had alien abduction experiences. Barbara is a licensed marriage and family therapist, certified hypnotherapist and regression therapist in Claremont, California. Nadine has worked as a litigation assistant and project coordinator for large business and public entity clients. Together they have written a book, entitled Alien Experiences, which describes 50 cases of alien encounter, including transcripts from actual regression sessions. Placed in context with increasing UFO sightings around the world, the information in this book will raise disturbing questions.
