The burgeoning market of gadgets and apps that promise to decode, record, or even influence your dreams, usually failing at all three. This includes headbands that flash lights during REM sleep to "lucid dream" (but just give you a headache), journals that claim to spot patterns (but just prove you dream about falling a lot), and the classic "dream catcher," a web-based filter that catches bad dreams with about the same effectiveness as a colander catches water. The ultimate dream technology would be a DVR for dreams, but so far, we only have blurry sketches drawn upon waking.
Dream Technologies Example: "I bought a dream technology headband that promised to let me control my dreams. I spent all night trying to will myself to dream about flying, but instead, the headband just recorded that I dreamed about being stuck in a meeting about spreadsheet formatting. Progress?"
