As is probably to be expected,

I dreamed about Saiyuki. Sanzo and Goku were separated from Gojyo and Hakkai after encountering a massive creature covered in blades (which looked more like it belonged in RahXephon). They wandered into a small town in which, several months earlier, the cherry trees had come into blossom, and never gone out again. A constant shower of petals fell, and sometimes they formed a solid wall through which you could step to enter a dream. In the dream you became a great hero fighting in an endless battle, and the people in the town stepped through it often, and came back talking excitedly to one another about their great deeds.

It was a sort of mediocre little town before, where most people tolerated each other and a few people liked or hated each other. But now they are united by their secret, and very happy. A dense, silvery white light suffuses the town, which seems to make even ugly and mundane things beautiful.

Sanzo grumpily informs Goku that they're going to have to burn down all the damn trees. That's what always happens when they show up someplace and find out something weird's making everybody happy - it's got to be evil somehow. They're probably fighting Gojyo and Hakkai in there, unless it's some kind of brainwashing thing that Ni came up with, or it's Zakuro again. It could be some totally random and unrelated piece of evil. It doesn't matter, the trees have to go. There's always something.

(He was wrong about Gojyo and Hakkai - they'd been captured by lizard people with pointed sticks. There were cutaways explaining this, because my dreams often follow extremely strict narrative structures, but they were kind of perfunctory, because the cherry blossoms thing was more important.)
