That cherished feeling of not feeling anything is an illusion. You don't know what it's like to feel nothing, you've felt something all your life, you don't die when you go to sleep, if you think being dead is like resting you will.......I was about to say "be disappointed" but that's the thing, you won't be that either. Feeling nothing is not the same as resting, you don't die when you go to bed.
Possibly. Or, if it's the last thing that you ever feel, perhaps it subjectively feels like an eternity.
Time dilation is a common effect as brain activity is reduced. Perhaps as brain activity approaches zero, time dilation approaches infinity. Sort of the "falling into a black hole" effect. So, while your death (time from failure of macrofunction to loss of all local brain function) might take only a few seconds, it might subjectively feel like it takes forever.
In any case, you didn't address the other two possibilities.
