The point on terminal lucidity is that consciousness seems to involve more than brain function. Credible reports that people who have insufficient brain function become lucid for the last day or so. Nobody knows exactly what's going on, but something unexpected is.
Nobody is lucid or conscious once the brain no longer functions. Some confuse the timing of reports during near death situations where the brain still has activity, albeit reduced....or during peak stress bursts. The patient is revived and reports an experience that they assume happened after 'death' but in reality the brain was still functioning.
Eben Alexander was one, but it turned out that his claims regarding timing were not quite accurate, to say the least.
Plus the near death experience can be simulated in healthy subjects..
