The Stuff(ing) of which Dreams Are Made

My alarm clock interrupted a dream, not about Winnie the Pooh per se, but about its background. One of the features was a bit off (A. A. Milne wrote for his son, not his grandson), but the map of the Middle East post-WWI would have been accurate.

Still and all, if I'm going to dream about early 20th century English literature, why couldn't the dream have been about Lady Chatterley's Lover, which I read in the past few months, rather than Winnie the Pooh, which I haven't read for years?
