When I discovered lichtenberg figures - the burst capillaries from a lightning strike causes a fern like pattern to appear on the skin of the person whose been struck. I figured it would be interesting if something like a near death experience could trigger some kind of untapped power in a person, too. It's not an all-together unique idea I think, lots of people have written about near-death experiences changing people.
