Okay, so you reject any and all of the "soft sciences". I get it. I cannot respect that view.
That is absolutely not what the PDF I linked to says. In fact he goes to great lengths to explain why is it
not at all the same as hypnosis!
Try reading the article to educate yourself as to what his research shows. Start at page 13 to give you a jump start. But of course, you won't, because he is just a professor of psychology, and not a physicist, so it's not real science and you get to just be dismissive of it that way.
Yes, evolution of theology. What is your problem with that? You don't think people's view of God have evolved, or developed over the ages?
I'd actually try to understand why he feels that way, and listen to him. I'd be curious, rather than dismissive. It could be he was mentally ill, or he had a genuine mystical experience. I had a direct experience of the Infinite, but I'm not mentally ill, and never have had issues with mental illness.
Being scientific means you should be curious, and not a scoffing cynic who thinks everyone has to be crazy because they see things, or think differently than yourself. That's Just being religious, not scientific. I'm not impressed by cynics. It's not true rationality. It's just fear claiming the shield of reason but not actually using it.
