In the middle of the night, I woke up briefly with a dream idea I was determined to remember in the morning.  It had something to do with the words zither, blither, wither, and slither, and how they could all be represented by a single picture (like a political cartoon).   I recall that the image would have been ring-shaped, to suggest zithering, blithering, withering, and slithering.  As with too many dream images, the details had faded by the time I got out of bed.  I'm left wondering what the image would have looked like.  Could it have been a droopy fool (a withered, blithering idiot) playing a zither in the shape of an Ouroboros (the snake slithering into a ring)?  As a bonus, the entire image could be dithered!
