Why are NDEs so different from each other?

Every person that has one is a human being, so wouldn't you expect the NDEs to be similar? I know that there are commonalities between some of them, but it seems that no 2 are exactly alike.

I don't really buy the brain chemistry aspect. If the brain goes haywire right before death, than wouldn't the there be a higher probability of it just producing unintelligible stimuli than producing a well defined experience? I think the idea that the experience is filtered and interperted by cultural beliefs probably makes the most sense. But thank you for taking the time to respond to my question.
