I had a dream last night that the missus & I went on vacation to some city in Eastern Europe (think Prague), and the main tourist attraction there was that, in one section of the big river that flowed through the town (a la the Thames or the Seine) there was a shallow part, and a group of local housecats had trained themselves to hold their breath & overcome their fear of water.
This allowed them to walk into the river and sink to the bottom, where they would sit perfectly still, like turtles, occasionally coming up for air, and feeding on the little minnows that would swim by. People would come from miles around to see the fishcats of Prague.
I like a dream that defies analysis.
