@Leonard,
I don't doubt this story, nor its meaning. However such stories are what scientists will generally call 'anecdotal'. They are stories, which may indeed be true. But there is no way to independently ascertain the truth or falsehood of the story, nor to re-create the circumstances in which it was told. This is the frustrating thing about researching these kinds of topics. How do you reproduce these types of things so that they can be examined? Won't stand up scientifically, and probably wouldn't stand up in a court of law, either. And that is the way us moderns run things.
I have an anecdote of my own. One morning in May this year I signed up for the free online New York Times because I wanted to read an article. Part of the registration, as is normal, was 'the security question that only you will know the answer to'. I picked 'First Pet Name', to which the answer was - 'Haaji'.
Now Haaji was a small black cross-breed, that we had when I was a boy. When we went overseas for a year, we left her with the neighbours. And when we came back, the little boy next door had bonded so much with the dog that my mother said he could keep her. She couldn't stand to take the dog back and upset this boy who was convinced the dog was his.
Of course us kids were just outraged. Screamed about it for days. "How can you take OUR dog?" No justice in the world. We got over it in time but we were never happy about it and it remained a sore point for years.
Cut to 2009. I visited Mum in the nursing home. She has very advanced senile dementure and rarely says anything. She has to be fed, lifted, cleaned, 'by at least two attendants' according to the notices next to her bed. Anyway I sat next to her that same day. After about 5 minutes, she suddenly said about the first thing she had said to me for many, many visits.
She said "Sorry about that dear".
"Sorry about what?", I said.
"About Haaji".
And that was it. The only thing she has said since is "you look nice today dear". Now of course this does not constitute "scientific evidence" of anything. I know how science works.
I also know what I heard.
