via bbc newsProspective dreamers are asked to look at a photo of what they would like to dream about and then record a story line into the Yumemi Kobo, or "dream workshop". The machine uses the voice recording, along with lights, music and smells, to help them direct their own dreams during periods of rapid eye movement (REM) sleep, Takara Co said. Sleepers are woken up gently after eight hours with music and lights that stimulate sunlight so that users of the gadget do not forget their dream in the shock of waking.
