In my case, in an ideal world I would never want to experience any dying process, I would just like to pass away in my sleep, that would certainly be ideal. While the thought of being dead is extremely comforting to me, the thought of actually going through a dying process unless it's by a very peaceful method sounds rather awful. But I know that for certain if I actually managed to go through with ctb I certainly wouldn't want to be placed back into this world to experience it all again, sounds like such a nightmare.
But I've never really been into any kind of self harm, I guess that we are all different.
