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.
