But the fact is this isn't a scientific expiriment, it is a non-replicatable event, and sometimes perception can be more real than science from a humanocentric perspective.
You actually repeat my point when you say 'the next question would be what are the odds of those sections being triggered randomly in an accident.' Likelihood is exactly the crux of the issue. Is it more likely that a mild concussion incurred during the crash affected his parietal lobe, or that he experienced magical reanimation?
Since concussions and vehicular crashes go hand in hand, and concussions have been known to affect the parietal lobe, the first case is quite likely.
Since magical reanimations have never been documented to even the lowest standards of international science, the second situation is extremely unlikely.
