I use the word "dreamed" advisedly, because Brave New World - gulped down whole - achieves an effect not unlike a controlled hallucination. All is surface; there is no depth. As you might expect from an author with impaired eyesight, the visual sense predominates: colours are intense, light and darkness vividly described. Sound is next in importance, especially during group ceremonies and orgies, and the viewing of "feelies" - movies in which you feel the sensations of those onscreen, "The Gorillas' Wedding" and "Sperm Whale's Love-Life" being sample titles. Scents are third - perfume wafts everywhere, and is dabbed here and there; one of the most poignant encounters between John the Savage and the lovely Lenina is the one in which he buries his worshipping face in her divinely scented undergarments while she herself is innocently sleeping, zonked out on a strong dose of soma, partly because she can't stand the awful real-life smells of the "reservation" where the new world has not been implemented.
