I’m still trying to get a handle on this story… and am also giving it the benefit of having been your dream… But it reminded me of a metahistory scholar (I can’t think of his name) who had a theory that the great poets/musicians throughout the ages lived near water… Sorry I can’t remember more about the theory than that. There’s also the possibility that living near bodies of water bring forth different tasks from the population. Instead of only hunting, gathering, farming etc there would also be fishing, sailing etc and all the industries that they require. Well, sounds like an interesting dream.
