Harvard Professor John Mack, a psychiatrist and a psychoanalyst, was intrigued by the number of cases in which he found clients reporting alien abductions. Of course, many people suffering from some form of psychosis might say that they were encountering Aliens. But what Dr. Mack found was that these people reporting abductions were not insane. They were coherent, rational, and functioned normally except that some reported stress and an overwhelming fear of the abductions.
Obviously, people can and do lie about their abduction experience in order to gain attention. But Dr. Mack reported,"I've now worked with over a hundred experiencers intensively. Which involves an initial two-hour or so screening interview before I do anything else. And in case after case after case, I've been impressed with the consistency of the story, the sincerity with which people tell their stories, the power of feelings connected with this, the self-doubt—all the appropriate responses that these people have to their experiences."
scary stuff...
