To me that is thinking inside that box of having to understand through our human mind and doesn't work.
I'm not sure if accounts of NDE talk about the state of the person experiencing it. What they generally describe is what they are seeing happening in the corporeal life and are not part of it anymore. They talk about feeling reluctantly called back to something they have left. Reluctantly.
Do you believe in the Universe? In Infinity? If your mind can actually wrap around something which we can't experience in corporeal life - I call that faith - then I suppose you can believe that you understand what life after death is/is not like.
See what I'm saying? Those concepts are outside the realm of measurement and experience and yet we posit them with our inadequate human brains. And, I daresay, some sense of fear. No wonder we'd like to think that we aren't energy which could exist forever!
Incidently, I am not making a case for life after death. I can't do that. No one can.
What I'm saying is that not all can be knowable.
