Doctors' estimates of the feasibility of preserving the dying for future revival

I thought about death the other day and how maybe it's akin to the feeling of going under before a surgery.

When you go under and then wake up some hours later, often you feel like no time has passed at all.

What if death is just that same feeling or lack thereof for Millenia, an infinite amount of time, but at some point from your perspective, you wake up instantly far in the future.

Like a photon travelling for millions of years, you don't perceive time passing at all.

Given an infinite amount of time, there will be a time where all of your atoms will recombine again in just the right away to bring you back to consciousness with all your memories in tact.

To you, it feels like you woke up in an instant. To the universe, it took an infinite amount of time to wake up you again.

As someone who once came extremely close to death and was unconscious for days after eventually receiving medical care, my take on death is that it's probably similar to what you're saying about going under for surgery. I'm somewhat neutral to mixed on having been revived, but I no longer fear death. I still have a fear of suffering and having painful final moments, but death itself seems peaceful if nothing else.

In terms of something happening after death, my only real thought on that is that it really troubles me that I came into existence in the first place and that I experience anything at all. I sometimes wonder if that was truly a one time thing or if it's something that could happen again.
