It is well known in medical circles that near death experiences usually leads to visions perceived as mystical. Sometimes the patient meets lost loved ones in what seems like the afterlife, sometime he meets them alongside still living loved ones...

Disturbing incoherences combined to empirical studies lead to the conclusion that the imminence of one's own death is just too much to bear for our survival-obsessed mind, and the brains reacts by drugging itself into comfortable hallucinations, as to make the horrible but (apparently) inevitable process somewhat bearable.

And "brain-dead" is just an expression. If he was still able to record experiences, it just means he wasn't dead yet.
