From where I'm sitting, it looks like death should not be the end in that case.
You can't perceive the passage of time when you are dead, so you're just going to experience dying and then immediate rebirth after the countless eons pass for that rare moment where entropy spontaneously reverses to form your mind again.
I'm saying that's fine, if you want to explain the unknown with mysticism who am I to say otherwise.
I'm just saying if you're using mysticism to explain the unknown you don't need science just by mystical. Either embracing a mystical tradition that believes in this sort of recurrence or creating one for yourself are both cooler than pseudoscience
I'm not really sure where I've done pseudoscience, I never put this forward as explanation for the way the universe works, I was just considering possibilities.
