Can I make a comment?
I had a similar experience when I converted to the cult. I used the PUSH thing- Pray Until Something Happens. I prayed hard for a long time, and then I felt a great comfort, all that wishy-wahsy stuff. Years later I started hallucinating.. and it's the same feeling sometimes. I now have figured out that when you pray hard or whatever, it sets you up for a self-induced hallucination. This is why people under stress praying hard experience things- their mind tricks them into feeling what they want to feel. IMO, simple as that.
Of course, in this person's case, the alcohol withdrawal probably added to it as well, making it even easier to hallucinate.
