Great Hamlet Dream

I had a dream last night -- it may have been a half-dream, as it was actually morning and I was nearly awake -- in which Hamlet had a twin sister, and they were shipwrecked. Weird bits of Twelfth Night conflated with Hamlet, Illyria superimposed upon Denmark, and some entanglement of Feste and the Grave-digger -- not Feste tossing up the skulls, which would be easy enough to envision, but something more elusive (or perhaps just forgotten).

I don't know whether this is a million-dollar idea sent down as a gift from the Great Unconscious, or a bit of codswallop washed up by the oil slicks of sleep. I think I have actually had this dream or half-dream before, and I remembered or recreated it. Obviously it resonates with something in my head, but not necessarily anyone else's.
