You said: "Out of body" experiences are caused, usually, by being the reality created in parietal brain. They are not physically real, but are real as it is only by or based on this directly experienced reality by which we INFER the physical world does exist."
Sure, but I disagree with OBE experience, you're wrong they are definitely real, although you can explain almost everything when it comes to OBE and NDE, science cannot explain how people actually see what is doctor doing as well as see all those instruments and monitors surrounding them?
This is not some hallucination of the brain created by anesthesia or anything else like drugs, people actually see what doctors are doing as well as what monitors are showing.
This is why it's impossible to know if there is some kind of life after physical death of the body.
Your text, now bold, is their claim and quite possibly their honest belief, but inconsistent with the physical laws one of which is valid detailed vision does not occur with the eyes closed so I would need testable proof, not a self report of something a doctor may have said, like: "The blood pressure is only 70 now." which could easily cause the patient to form an image (in his mind) of a gauge with needle pointing at 70. (It is hard for me not to form that image, just by writing this. What about you? Did you form a mental image of a gauge when reading?)
Do you have a link to any well controlled reports of these miracles (knowledge not possible for the patient to have by regular means)? I agree that some people do recall things that were said while they were in a coma, etc. That is rare and strange, but no miracle.
I claim OBE & NDE are experience created (as all experiences are) in the Real Time Simulation running in the parietal brain, and as the only direct knowledge humans have, in some sense, are more "real" than the physical world which is INFERRED to exist from these direct experiences (but may not exist as Bishop Berkeley argued logically and completely consistently that the physical world inferred does not actually exist more than 300 years ago).
I have a Ph.D. in physics and believe the physical world does exist without any miracles (violations of physical laws, many of which are well known to man). For example, that there is an force* (gravity) between all mass pairs. Thus if someone´s OBE has their body "floating" just below the ceiling then I say (assuming they are not lying) that is part of their parietal created reality but not a physical reality that occurred as it would be a violation of the laws of gravity.
It is interesting to understand why Bishop Berkeley thought the non-existing physical world that God was causing him to experience appeared to very consistently follow a set of physical laws. The good bishop noted that only if the physical world appeared to have seldom violated regular laws (rules of behavior) could God work miracles when he chose to. I.e. miracles, are by definition, violations of the physical laws and thus miracles could not happen if there were no physical laws, which are almost always consistently obeyed.
Berkeley was very logical and intelligent and did not accept the reality of the physical world. - From where and how would all that mass come from? ** Many philosophers and others have tried to find a flaw in Berkeley´s logic or some how show that the physical world does indeed exist, but in more than 300 years none have! One famous attempt was a man who kicked a stone and said, with minor pain in his toe: "I demonstrate the world is real, thus!" but of course that, like all the other attacks on Berkeley´s POV proves nothing. - God gave him that experience of pain in his toe and the visual experience of the stone flying forward, etc. as at that time God did not want to make a miracle.
* One can describe it as a mass warping of space, instead of a "force" if one likes a more modern POV, but either description results in the same attractive acceleration on objects free to move. (Like the two descriptions of 12 vs a dozen eggs - either is the same to the cook.)
** This question remains unanswered to this day but in modern terms the question becomes: "From where did all the energy of the "big bang" come from?" Berkeley had a logical correct answer, consistent with his Christian faith, but physicists, like me, do not.
