No. Consciousness may be mysterious, but the near-death experience is more than just mysterious as it is screaming that it is not caused by the brain. Not only is there plenty of scientific evidence that the brain couldn't possibly create it, such as people accurately reporting things during OBEs (see the AWARE study and the book The Self Does Not Die, for instance), but there is also the fact that the near-death experience convinces EVERYBODY who has it, even extreme skeptics, neuroscientists, and ultraantitheists, that the afterlife is real.
NDErs are representative of the population as a whole, all are convinced, so 100% of the population agrees that the afterlife is real once they have an NDE themselves. Hence, as this article points out,
>"[A]t least some NDErs were equally as skeptical of the existence of an afterlife or of the idea that NDEs are or can be indicative of an afterlife as we may be now, and at least some of them also shared the intensity of that skepticism, and at least some of them also shared whatever justifications we may think or feel that we have for that skepticism. And yet, the NDE thoroughly and justifiably convinced them that there really is an afterlife for experientially self-evident and realer than real attributes of the experience."
The NDE is literally the allegory of the cave of the modern times. These people have experienced an unmistakable higher reality in the light of the NDE world, and when they come back to tell the people still living and immersed in this world, they are met with disbelief, ridicule, and even hostility. How comical is it not that the skeptics do not see the irony in that?
