A curious aspect of Near Death Experiences

[Naturally]

When I got burned and while in intensive care, I was clinically dead and brought back 3 seperate times. Didn't see a thing, didn't float... nothing.

That is an important point, and I am glad you shared it. Not having an experience is also an experience, and it deserves the same respect as those who describe something vivid.

What interests me about near death accounts is not the claim that everyone must see something, but that some do, and that those experiences show patterns across very different people. The absence of an experience does not invalidate the presence of one any more than dreaming every night is required for dreams to exist. Some say they don't dream at all or don't remember dreams.

It may also be that consciousness under extreme trauma is not one single thing. Shock, medication, brain injury, or the speed of the event itself could all play a role. Even people who survive cardiac arrest under similar conditions report very different things.

These accounts taken together raise questions rather than settle them. And your experience is part of that picture, too.
