I knew and shared beers and war stories with a guy this happened to. He was struck by lightning. Pronounced dead in the ER -- they put him on a gurney and he woke up in the hall, with a sheet over his face, listening to people talking about taking his body to the morgue. At that point he still couldn't move his arms or legs, but he could breathe, so he started blowing on the sheet as hard as he could, and somebody finally noticed the sheet moving. He eventually made a fairly complete recovery and became a motivational speaker.
He wrote a book, which was made into a movie.
