That it happens at all is remarkable.
Spoken like someone with zero understanding of neuroscience. You take a brain, you reduce its oxygen intake (as happens in the physically stressful situations that induce "near-death"), and you get hallucinations. No supernatural entities need apply.
Tunnel vision (including the cliche "white light") is very commonly reported among pilots pulling high-G, which is a nicely repeatable way of temporarily reducing blood (and therefore oxygen) flow to the brain.
You know this to be notable. You know this is evidence. If you say otherwise, you know you are lying.
My, that's a shiny crystal ball you have there. By your own testimony, you're clearly under the delusion that you know exactly what GP knows/thinks.
Typical theist LOLgic.
