I read Whitley Streiber's Communion, Transformation, and Secret School. (Hey - To all the skeptics out there, I needed something to read as escape at circuit and district assemblies, being the whipped teen that I was). If your or your hubby haven't read the later books, maybe you'll find Streiber's changing views on the intentions of his visitors, to be a small release for any anxiety he may have over his own experiences. I personally have never had such a thing happen to me.
If you're interested at looking at the "Visitor" phenomenon from a different perspective, I suggest Passport to Magonia from Jacque Vallee. It will show you alot of similarities between the modern alien/ufo experiences and folklore from the past. He has his ideas on whats behind it all. You can draw your own.

There's a body of lore thats growing in the field of ufos and aliens that has gnostic overtones. In particular with forces of light, (like the Nordic Aliens, or even angels) trying to reveal life-saving information to us, while in struggle with dark forces (like the Greys, or demons or archons) that only wish to exploit and keep humans trapped for their own ends. Gnosticism goes with anything, much like ketchup, and I love them both.
