Well, "clinically dead" isn't necessarily "brain dead", but even then, what is the evidence that the NDE occurred during the "dead" time, and not, say, right before or right after?
Exactly.
If you have ever been out drinking and had more then is probably wise, then you are quite likely to know that your experience and perception of the flow of time and events can become distorted and un-reliable. Like wise when you are chronically ill with flu or worse you can loose track of where and when things happen.
With NDEs there is no clear cut evidence that any of these memories come from the point where the brain is shut down. As has been said ‘clinically dead’ doesn’t necessarily mean no brain activity what so ever. There could be far, far lower than normal activity; enough for the doctors to use the label ‘clinically dead’ as it’s clear they can’t continue to function at that level, off the machines.
So as there is quite strong doubt that these experiences occur in periods of zero brain activity, and are thought to occur in a very low state of brain activity or in the activity between periods of zero activity, then there is nothing concrete to tie claims of the consciousness existing separate from the brain to.
I apologise for the use of the word ‘silly’, that was wrong of me.
Our brains are fantastically complicated things and thanks to the highly complex wiring inside, our minds, personality and consciousness are all emergent properties of this wonderful organ. We, currently have nowhere near a complete understanding of the totality of its workings. To assume otherwise would be folly. Like wise to assume that consciousness exists as something separate from mind & body, on the evidence we have is also tantamount to folly, as any claimed evidence is anecdotal at best.
Yes people have varying experiences but as your linked article said:
BBC articleThey told of feelings of peace and joy, time speeded up, heightened senses, lost awareness of body, seeing a bright light, entering another world, encountering a mystical being and coming to "a point of no return".
This does fit the generally accepted notion of an NDE, does it not? Particulars may be different here and there but the general theme does tend to be similar.
I don’t blame people for wanting to believe in what NDE reports seem to show as it does seem a natural urge for the human animal to seek conformation of some kind of continuation after this mortal existence. But as far as I can see the evidence is not there.
Now is you could do an experiment where you could verify some one had absolutely zero brain activity (brain death) and during this time read them a unique passage of text. Then if they recover and subsequently recall this bit of text THEN a case might well be made. But only if there is not the slightest trickle of activity in the patient’s brain.
