An exception - if I may :)

People I love and have lost have not told me that they dreamt about death. They mostly had the same dreams young people have

Of course, I would love it if your theory is correct, as, at 76yo, I still have dreams about me being in school (failing my exams)...if I am being prepared to be young again, all I can say then is...dream on, who cares if I fail?!

I love it :)
