People who have died briefly, what did you hear, see, and feel?

At the moment of apparent death, I levitated from my body which was submerged under 3 feet of lake water on a clear springtime morning. As I knelt beside my physical self lying flat on it's back in the sand under the water, I remember how unusual it felt for me to witness seeing my body as others would have seen my physical self in my day to day life.
