Swimming Up to the Ocean Floor
In high school I was swimming in the ocean when a big set came in. I swam towards a giant wave and dove deep to swim under it, but was still pummeled in the washing machine as it crashed overhead. When it had passed I swam hard to the surface, but instead my chin hit the sand. I had swam down thinking it was up. Startled, I flipped over and used my feet to push my body up to the air.
