indeed, that could catch some flack but i will try to not give you too much =D
a scientific explanation? random synaptic firings and flashs of memories as the brain slowly fades away. thats all i can think, and would also explain why so many peoples near death experiences have commonalities (3rd person perspective, life-before-my-eyes stories, etc).
now this is not to dumb down your miracle at all. it sounds to me like you were quite lucky and that, just maybe, dare i say divine intervention? lol either way, still a miracle. and, scientific 'theory' aside, i hope your right =D
