A duo of developers from Brooklyn, New York, have built a sleeping mask designed to allow people to have lucid dreams that they can control. While it may look like a standard sleeping mask, Remee has been billed as a special REM (Rapid Eye Movement) enhancing device that is supposed to help steer the sleeper into lucid dreaming by making the brain aware that it is dreaming. The goal of the product is to allow people to have the dreams of their choice, from driving a race car to flying to having lunch with Abraham Lincoln. The inside of the sleeping mask features a series of six red LED lights that are too faint to wake the sleeper up, but visible enough for the brain to register them. The lights can be programed to produce a sequence designed by the user. Sleep stages are divided into two main categories: non-REM and REM. People go back and forth between these stages throughout the night, with REM stages, where most dreaming occurs, lasting the longest towards morning. Remee apparently notices these longer REM stages and 'enters' the dream via the flashing lights. The device will wait for four to five hours for the sleeper to get into the heavy REM stages before the red lights turn on. The idea is simple: you are playing a perfect round of golf in a dream, and you see a pattern of red lights flashing in the distance. Because the pattern is in a particular sequence, it would signal to you that you are dreaming. Once you realize you are in a dream, you can then decide what happens next, whether it be a quick trip to Antarctica or time travel.
