Ye sure, but I think those people having been 'already' dead and than were brought to live again saw such things and had told it later.
One can interpret it as "searching" of the brain for a solution for such a heavy attack on it (death is one of the worst attacks, though its the last ^^). It trys to find any similarities in any situation of your whole life, what makes you thinking of a live review. The matter that you only see the positive aspects is explained simple: the brain is designed to save the good things better than the bad.

No matter what happens AT THE MOMENT of death, after it there's nothing, I agree with you
