Nightmare

So yesterday/Sunday morning -- I think it was then -- I woke up really early due to a nightmare.  I don't remember the premise, but I was at a public pool.  Do you know they make you douse yourself in water before jumping into the pool?  I remember when my family was visiting family in Los Angeles, and we went to a pool, and a lifeguard ordered me to go to a shower before jumping in.  Well, I think that in this nightmare some dude told me the same thing.

And that's all I remember.
