So the other thing is the idea that a discarnate consciousness would work that way - would be able to float up to the ceiling and look at something there and report back . . . but this is odd because it's the idea that a discarnate consciousness is just another kind of body that moves in three dimensional space - but one that can float and is invisible and (insert other properties here) - this is in line with some of the kinds of ethereal bodies postulated in traditional ideas . . . but other kinds of subtle bodies or other forms of consciousness, it's not claimed they work this way - so why do we think that if there is consciousness apart from the body it could and would perform the above task and that if it can't then we've proven that consciousness is localized to the brain?I'm not sure what "exotic" possibilities you might be referring to, but I don't think we can rule out every other possibility in the universe. I just think it would be substantial evidence that might allow for some progress. The reason that I believe it would be substantial, is that in conjunction with other verifiable, but less definitive evidence, such as times, locations, and numerous details about the deceased person's life, what other explanation could there be apart from an elaborate hoax, either by the claimant, or by some clandestine third party?
Again the problem of mixing paradigms. So we do have assumptions in the above experiment - that consciousness, if it exists outside of the body, will orient itself in time and space the same way that physical bodies do and will remember or decide to go up to the ceiling, get the message and promptly return to the body - I'm assuming this is all at the will of the subject. And certainly anyway making that specific claim - the above is an appropriate test. But it doesn't seem appropriate for an NDE OOBE for example where the claim is that consciousness has suddenly (and perhaps traumatically) untethered itself from the body. If a sense of self oriented to that body is even retained . . . and based on reports of OOBEs and NDEs, people have all kinds of weird experiences - in many cases they don't seem to line up with an entity oriented to three dimensional space and time as we know it. Of course that doesn't prove it isn't a hallucination - but without a way to detect and validate that it is moving through some of kind other dimension or something, we can't really determine this from a materialist paradigm. Hagelin's idea of shadow matter is intriguing because he says they do have experiments planned at the LHC when it powers back up.
