A Japanese smartphone app, the Yumemiru, lets you maximize the time you spend every night just sleeping. Yumemiru takes the self-help craze of the nineties to new scientific heights by leveraging the bundle of sensors in your smartphone. The app utilizes microphones to detect when the user is in REM sleep, the point in the night when you begin dreaming and also the moment when you are most susceptible to suggestion.
The free app has 8 different scenarios to choose from including a walk in the forest, getting rich, flying and for those romantically disposed, a scenario that stimulates dreams of love tailored for both men and women. After selecting the type of dream you want to drift off into the app runs in the background and detects the time passed before you go into REM sleep.
Once you’ve entered REM sleep the soundtrack begins to stimulate your dreams.
