I see a lot of attempts to either validate or discredit these descriptions of NDEs by comparing the details that are related to other people's NDEs or other sources of description of what lies beyond this mortal experience. What they are failing to take into account is that the descriptions are all given when the subject is back in their bodies and using their brains and the tools of ordinary language to attempt to describe their experience to people who have never had one.
It is not necessarily the case that what they experienced was actually different just because the descriptions they give when back in the ordinary realm of life contain different details and varied analogies. They certainly must be analogies since they all say they are trying to describe something that doesn't exist in any way shape or form here in our ordinary state.
You expressed the commonality of reported experiences very well.
