The bluebells made such a pool that the earth had become like water, and all the trees and bushes seemed to have grown out of the water. And the sky above seemed to have fallen down on to the earth floor; and I didn’t know if the sky was the earth or the earth was water. I had been turned upside down. I had to hold the rock with my fingernails to stop me falling into the sky of the earth or the water of the sky. But I couldn’t hold on.
