Cities in the Astral

I had an adventure that was at the edge of semilucid (kind of knew it was a dream, but mostly just let it ride) The final scene involves me and my wife in a row of huts near a beah. She is feeding fish. Every fish gets eaten by a bigger one. The surf runs in and out between huts, until sharks come. Swirling wonderful sharks of all sizes. The tide is getting high so we go in a hut. The hut get torn loose and we have to jump out. Way more to the story but the shark part was very vivid.
