First and foremost, I love reading other people's ways of seeing the world. In this case, your vision of what happened is what I felt myself years ago, although not now.
Now, important: 99% of the world's illnesses and ailments have their origin in the mind.
It's hard to accept this, because it means that, really, could someone with cancer heal if they set their mind to it?
The answer is yes. But that doesn't mean it's easy, or that it works for everyone.
Regarding that type of therapy you went to, I have a good friend who does it for those she considers need it. And, it works, although only temporarily, as a patch. The thing is how it's done. She does it differently than you have described in your experience, and I must say that it works.
In my example, we went to the mountains, to go hiking, but there came a point where we wanted to go higher, but to do so, we had to cross a fairly narrow, but viable, precipice. It's not that it was difficult, but it was dizzying because of the fall that could be seen. My wife was rooted to the spot, scared. She couldn't move!! Right there, our friend did her arm therapy on her, and her fear disappeared, and she jumped like a goat over the rocks and subsequent falls.
And, regarding curious spiritual experiences, I myself have those experiences. I do soul channeling (that is, I talk to people's souls), and, although it's hard to believe, it's true.
I have proof not in one, but in several people to whom I did their channeling. They were people I DID NOT know at all. It was the first time in my life that I saw them and spoke to them, I knew nothing about them.
In the channeling, I receive messages of events or desires that only that person knows. The faces of surprise and tears mix when I finish my channelings. Tears appear because they have a response to something that was blocking them, and they have been a recurring thing on many occasions.
Certainly, not all people are affected by the channeling in the same way. There have been some who have simply said thank you with a smile and left.
To finish: The subtle world is more real than we think.
