The dreamland is supposed to be a play off her childhood darkened by her future. Considering that, you could think of the happier moments as Alice in Wonderland, involving some more ridiculous scenes and the darker moments as Tolkien during scenes like the Barrow Wight or anything to do with Mordor. I'm considering what kind of balance I want between the two, but what's certain right now is that there will be large elements of both.
