When I was about 10 I got stuck in the ocean once at a beach. Even without big waves I kept getting pulled further from shore and wasn't strong enough to break past the current despite being a decent swimmer (enough to pass various tests and get certified for some level of swimming from a local camp). I still have flashes of memories of looking back at the shore and it being quite far but not abnormally far. I just remember treading water for a pretty long time and having to signal the lifeguards with my arms. I'm happy they came eventually.
