I’ve never heard of him to be honest. Just looked him up. I don’t know much about that angle (psychology). I just don’t believe there are aliens visiting us in such ways. I’m not saying I don’t believe there could be aliens out in the universe. If God wanted them to be there, they would be. (That’s my big problem with Drake’s equation: You need to multiply by the God variable; 1 if He wants them to exist, 0 if He doesn’t.)
Concluded that he wasn't quite sure "what" was going on with the abductees, but something very real was taking place.
I have read his accounts and they provide a completely different perspective on all this stuff.
