Jaymie's experience sounds like a lot of NDEs
Indeed it does. The reasons these experiences are common could be because all of these people have had a taste of afterlife - surpassing to a realm we all hope exist...
But i'm afraid i'm going to crap all over this school of thought and get scientific. It could also be that these people are all having a common near-death factor - an instinctual
chemical reaction in the brain to help them survive.
From a neurobiological point of view, a NDE like the one told doesn't make sense. The memory is physical, when you leave this reality you should have left your memory behind in a complex of dead neurons. If i remember correctly the "light at the end" of the tunnel feeling, is infact a chemical reaction to do with serotonin (going to have to look into that a bit more)
What would make sense to me is...
The person is dying. They are aware that they are dying and it may well be the very end. The brain, disorientated enough, attempts one final instinctual action to motivate the individual. It creates a figure or voice of respect that the person will listen too. (in your case, your grandfather) and that figure says the right things to help you survive.
The reason I hold this view, is because I myself had a near-death experience - well the thing is i wasn't actually anywhere near death - I just thought I was. I had a huge panic attack after some marijuana. After about 3 hours of what felt like I was fighting for my life, I was so exhausted from all the fear I assumed I was near death. A voice - that of a wise 40 yr old - started speaking to me, asking questions like "What were your golden memories of life", "What did you learn from your experiences". It was then when I realised I was too young to die and wanted to live which gave me motivation again.
Okay so i was mentally ill and on drugs, but it's an example of how the brain can take over when you consider yourself near death.
