“This usually occurs at the moment when my head hits the pillow at night; my eyes close and … I see imagery. I do not mean pictures; more usually they are patterns or textures, such as repeated shapes, or shadows of shapes, or an item from an image, such as grass from a landscape or wood grain, wavelets or raindrops … transformed in the most extraordinary ways at a great speed. Shapes are replicated, multiplied, reversed in negative, etc. Color is added, tinted, subtracted. Textures are the most fascinating; grass becomes fur becomes hair follicles becomes waving, dancing lines of light, and a hundred other variations and all the subtle gradients between them that my words are too coarse to describe.”
