The act of swimming in the early morning while still mentally asleep. Sleep Swimming is often seen at pools where swim teams practice at absurd hours of the day. It can also be known as swimming with your eyes closed while moving your arms and legs attempting to just survive until practice is over.
Me: Do we really have to have morning practice right after this eight hour bus ride!?

Teammate: Yeah dude I think so. It's going to be bad!

Me: Well if it's really true then i'm straight up Sleep Swimming!
