Incredibly easy to explain this without trying hard. The subject has some sense of movement forwards, and the brain rationalises it, like we do in dreams, imagining a tunnel or a canoe or whatever familiar thing is associated with that feeling of drifting or flying. So we can conclude that maybe near death experiences cause a feeling of falling or drifting, and is a bit like dreaming - not that objective reality should be rejected.

We're talking past each other. The problem isn't coming up with a hypothesis of why experiences differ according to experiences. Start by explaining how there can be any experience at all after an hour without oxygen to the brain. But after that we come to a stage where experiences differ so much that they aren't reconcilable in one objective reality and that's what I tried to address.

How would we determine that the experience happened during that time and not as a memory created when oxygen reached the brain after, or so on? If you assume that narrative memory is a little bit hallucinated (which I think is pretty observable, try dissociating a little and you can experience it) then many options are on the table.

Besides the clear possibility that the memory forms later, the brains of people who report NDEs have never stopped - there is no report of anyone ever recovering from brain death (as in, from a basically flat EEG).

Some cells are still technically alive after 1 hour mark in the sense that there is no necrosis and cell membrane is still operating. This depends on cell type and nourishment - for example cells that have high amount of CoQ10 can live longer etc.

In any case, brain is definitely NOT 100% dead in a sense that ALL of its cells are necrotic which might explain why it is in a dream like state.

Also, I doubt 1 hour mark is regular thing in NDE.
