I was intrigued by Pauline's post "Life with the aliens part two," describing Jenny Randles' observations on 'vasovagal syncope.'
Like Pauline, I am starting to wonder if there aren't a number of pathways to alien abduction experiences. Perhaps sleep paralysis; hypnagogic imagery; migraine prodromes and auras; fantasy proneness ; vasovagal syncope, and other yet unknown factors, might all be entry points to such an experience. Perhaps, then cultural expectation, personal belief systems and interaction with UFO researchers turns the original observation into a UFO abduction/contact?
In my opinion, future study of individuals who report alien contacts could perhaps follow the sort of methodology which I outlined in my post dated 5 Oct 2010, and obtain a detailed medical history; using the above list of items as a starting point.
This is the sort of research which could assist eliminate the more mundane potential explanations for alien abductions/contacts, leaving us with a better perspective on those cases which survive this screening process.
