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.

I prefer the Buddhist interpretation of self. There isn't really a singular you. We are all interdependent beings. A four plus dimensional tree reaching back to the start of time. The "you" that you're experiencing right now is an illusion created by your brain. When the body you are currently experiencing with dies, there are still all the other bodies producing experience.

After all, are you really the same person that began your life? Do you have the same memories? Can you even remember what being 10 years old was like? Are those memories real? Are you experiencing the same universe as when you were born?

For all you know, you have died a thousand times and just don't remember it because those memories died in some other universe or some other body.
