I'm in the water at coed.
An event is happening. Its a wedding procession ceremony or something similar, and I am helping with the procession.
Me and my brother and a friend have to swim to the other side of the lake, where the swans are entering. As the wedding procession comes down the hill, the swans are let out and they all enter the lake. It is our job to make sure they go in the right direction. When we get to the other shore of the lake, we find that they are all women, and they enter the lake as women, and by the time they reach the other side they have become swans.
My friend Alys is one of the swans, and she dives into the lake like a fish.
I watch as more women come down the hill and enter the water.
