There was a neuroscientist who had a terrible case of bacterial meningitis. The infection became all pervasive and white blood cells by the millions came and released chemical agents to kill the bacteria and then died. His brain was entirely coated with pus. Then he went into brain death and there was no activity. His intellect was gone.

And yet, he recovered and recounted that he had very complex dreams for many days. That's impossible from what we know of science for the brain was too damaged to have higher order thinking.

I think he came face to face with his consciousness or soul, and that likely the soul doesn't die, only is released from this shell we inhabit during Life.

Something mysterious exists beyond this world and this Life.
