Your English is better than you think. Your concept #2 seems fairly clearly to be a version of interactive dualism, with the "true source" or "unseen structures" being something like the Spiritualist's "subtle body". I disagree that all the data collected (i.e. empirical evidence) endorse your concept #1. There is an immense amount of empirical evidence for the phenomena of parapsychology, including childrens' past life memories, veridical mediumistic communications, and veridical NDEs. All this data is incompatible with the materialist neuroscientific view that human consciousness is purely the data processing of, or is one and the same as, the physical brain's neurons and synapses.
Years by years, I have read a lot of nde, past life memories accounts, but all in English languages. The people in those accounts might be from different countries and ethnics, but the narrations were all in English languages.
If those accounts had been written (first hand written excluding translated) in my mother language, I would have been much more intensively sensitive on many subtle aspects of them.
Like, I would have a sense that whether those accounts had been written in a "novel style", in a "story build", in a "pretentious posture",
in a "mincing attitude",
in an "urgent propagating and preaching inclination",
in a "bias stance",
in an "extravagant atmosphere",
in a "hidden special purpose",
in a "whimsy streak",
in a "paranoid and stubborn precognition",
in a "thick religious or political background",
in a "plethora of narcissism",
in a "self oriented spiritual therapy",
in an "euphoric abnormality",
written by a "not serious romping pupil", etcetera.
But in English language, all those sensitive perceptions for subtle aspects are absent or dimmed to me. Because a person's understanding of a language not written in his mother tongue, is limited in many subtle aspects. One can seldom understand a foreign language as comprehensive as his mother language.
However, within the most recent one year or two, I have read several nde accounts written by my native people in my mother language. That's important. At least that gave me a hard evidence that "near death experiences" are not western bubbles generated in the bathroom.
I can tell, there is no overt or obvious superstitious trace in those several nde accounts from native of mine, and the writing was not like by a not serious romping pupil. Considering that my mother country was super superstitious in history, a shameful history with low education rate and less civilized civilization in scientific fields, with many ancient archives left untrustworthy, I think those several accounts are a milestone demonstration to me that nde is a widely existent phenomenon spread all over the world.
I can not tell whether those narrators are honest, or whether their points of view are prudent, rational. But this gives me an impression that nde is a very very unusual phenomenon, not like a voodoo ritual in a tribe, which can be easily explained as a simple cultural product out of primitive ignorance.
When I read you saying "an immense amount of empirical evidence for the phenomena of parapsychology, including...." I thought perhaps you reminded and brought up to me that it couldn't be that so many people are all frauds or whimsy streak minded at the same time, if by any means it is so, then there must be an unusual reason behind this big international coax. At least nde is such unusual kind of phenomenon viewed in this way. Why so many vivid experiences happened in a situation where there should have been no vivid experience, and why many experiencers believe it is real unanimously, with also many exceptions but still consider it as unusually vivid, though.
