What's the closest you ever came to dying?

[Peh]

I don't know if it really happened, but back in the old days when I was 9 years old we had swimming lessons at school. We were kinda fooling around near the end of the lesson and I was at the corner doing some diving when some other kid jumped into the water and hit me. The next thing I remember is that I was lying outside the water while the teacher was beside me checking on me and some other kids standing around us. When it seemed I was OK they left and I was kinda alone. I went slowly back into the water asking myself what this was all about...No one mentioned that something like that ever happened to me, so I am not sure myself. Must be a fake memory.
