Disillusionment of Ten O'Clock
(2) Sea Level
Once you know the meaning of "ceintures," then you've got total access to the poem. Just sit back and let your imagination take over. Don't worry about trying to make sense of what it means to dream of periwinkles or what red weather describes. Those images are supposed to be abstract and provocative, meaning they are there to get you thinking about weird stuff. So revel in the weird. Revel!
