A lot of my dreams are set on coasts. Almost always a western coast, like in Oregon or California: I get different coasts enough that I seem to notice when it is facing a different way. (I recall a dream where I specifically thought to myself This is a south-facing coast, like the Gulf Coast or East Africa.) It's often, seemingly, the same stretch of coast, changed by who is there and perhaps which ships are sailing by.
I revisited a particular stretch of coast in dreams last night. How did I know it was the same?
I found a stash of recycled newspaper clippings that I'd saved.
