For their to be an evolutionary reason for it, it has to increase fitness in some fashion. Roughly speaking, it has to increase the chances of propagating your genes. It seems very unlikely that the character of "near death experiences" could have an impact upon fitness. Saying that something doesn't have an evolutionary reason is not the same as saying it's just coincidence. Our bodies (including our brains) are very complex interconnected processes. There's going to be all sorts of effects when those processes break down, and even if those don't have an evolutionary purpose, that doesn't mean they're just coincidence. This is a factual matter, which has nothing to do with an argument being bleak or not.
