In the height of my suffering, I had recurring, very elaborate death fantasies. I wanted big white bed with bright white sheets, fluffy white pillows, and big wooden posts. I wanted this in a house in some far away place, right next to the ocean. My fantasies were divorced from the practical realities of CTB and divorced from reality in general, and I just dreamed. I thought that somehow I could have a nitrogen pump that would slowly fill the room up, and that somehow I could just very slowly fade away. I could have music playing, and I pictured myself laying there and gradually turning pale or maybe turning blue.
I wanted to feel the relief of dying over a prolonged period of time, and it felt like such bliss to think of this. Then what eventually happened is I started to have problems with my heart. I nearly died in my sleep several times. I would wake up and my whole system would be vibrating, and I would feel like I was about to go. This was accompanied by an instinctual terror that I'd never felt before and that was unlike anything that I'd ever known. It was a terrible realization, that this is what I would feel in my last moments on earth. I experienced what it is like to die.
Peaceful ways out may not trigger this. What is needed, I think, is for your brain and body to not know that you're about to die. I'm not sure though, and this business of dying seems like something where you cannot escape some amount of emotional and/or physical pain.
