I was swimming in an outdoor pool. I was doing crawl, and going ludicrously fast. I'd lost track of the time, night had fallen. Someone looked at me with a look that said "you're still here"? Everybody else had already left quite a while ago.

I remember diving in this pool, and it was impossibly deep. Like the closet leading to Narnia, this pool was at least a hundred feet deep, had rocks and algae in it, and had all sorts of fish in it... even some extremely large species the size of whales... it was actually kind of creepy, in the typical way deep water always scares me. The unknown, not knowing what's lurking in the dark beneath you. You could not see the bottom of this pool, and large beasts lurked everywhere.

I got out of the pool at the end, and walked over to (presumably) my towel to dry myself.
