I remember when I was jumping on a water trampoline thing in a lake, and I jumped too far over on one side and it flipped over on top of me. It was too heavy to lift up and I was like 12 and stupid and forgot I could've swam under it.
So, I panicked and passed out and nearly drowned. I didn't float up when I passed out because I was under the trampoline. Nobody could find me because the water was so unclear. I was under water for like 5 minutes.
Not long, but I could've died that day within a few more seconds.

Thats is some crazy stuff man. And Ive never head a near death experience.
