Sleep experts say we can seize control of our dreams and do all fantastical things – fly, relive favorite memories, eat a mountain of ice cream – but only after we realize we’re actually dreaming. Achieving this deep – sleep state, known as lucid dreaming, isn’t easy. Wanna be dream masters practice every night for years and still never achieve success. A variety of masks and headbands promise to help sleepers reach a lucid state by flashing tiny lights above the eyelids. Sleep researchers, meanwhile, are researching other methods of triggering dreams.
