Swimming Dream

I dreamt I was in some kind of swimming club. The group was organized to perform synchronized swimming, but it was pretty casual. The group was small, maybe six people, mostly girls, we met once and then there were supposed to be a couple of practice sessions which I missed. I showed up for the 'performance'. The leader was not upset, I think she was glad that I showed up. I asked what we were going to do. She wanted a pencil and paper, but we're by the pool in our swimsuits and there's no paper or pencils at hand. I ask her to just show me by drawing on my hand with her fingers and she does. Four of us are to form a square in one corner of the pool and then swim along all four sides of the pool, maintaining our square. Then we would form two lines, one across each end of the pool and swim towards each other where we would form one line across the middle. Somewhere in here her fingers turned into colored dots and the lines she had traced became visible. After that it became very convoluted. We never actually got in the water before I woke up.

Once upon a time I used to go swimming fairly often, but I haven't been in years.
