Oh I don't know, how things look on the outside is often very different than how things are experienced on the inside.
When I was a kid, I somehow slammed my hand into a closed car door. As my parents turned to open the door and get me out, I remember everything got really slow. I looked at the closed car door, and saw my own hand disappearing into it, and it made no sense. My hand couldn't fit in there, there just wasn't any room for it. Then the door was popped open and my hand came out, crumpled and numb and, ultimate, incredibly completely unhurt except for some bruising.
My family members who saw the whole thing were freaked. I was freaked. The visual was out of a horror movie. Yet - on the inside, the whole thing was distant and numb and unreal, like a movie, the whole time.
Later I learned about shock, etc. which is the biological explanation. But the experience was incredible. And I've often wondered, when we hear of some apparently horrible death, how much of it was actually horrible, and how much not, for the person going through it.
Personally, I think that the body is the source of the suffering. To the extent the body is held on to, that life is fought for, there's going to be suffering. But to the extent that an inner separation takes place, the suffering ends with the separation from the body, no matter how it looks on the outside.
So don't be so pessimistic! Dying might be the funnest experience you ever have - but of course, you won't be able to tell anyone about it. And on the other side, everyone will just say, "yeah, we already know, it was great." Frustrating, eh? LOL!
Thanx for putting into words something I .. and I think many others .. have experienced
