I understand what you say but I'm actually thankful that I 'went through it'. It was probably the most peaceful and self aware experience I have ever had. Weird as it may sound it was like I was outside of my body watching what the doctors were trying but that didn't seem important. They gave up and started shutting down monitors as I was flat lined. During this I was having a conversation with something I can't begin to describe. I was asked if I had done what I was supposed to do and I answered 'no'. When I said 'no' my heart and breathing started again and I was totally OK the next day.
There are just some things that we can only describe as they are impossible to explain to one that has no concept of the experience. The result of my experience with all this is that I have absolutely no fear of death as I've already been there and had a conversation with whatever it was that I talked. Since then I've known that death is not the end but just a new beginning and I have no fear of this. The way I see it is, if there is nothing beyond our current existence, to what was I speaking?
