The idea behind the app is based on a very simple yet efficient principle: since your hearing works during shallow phases of your sleep, youre able to hear suggestions. One such powerful suggestion is played every 12 or 15 minutes in your sleep and if it just so happens that youre in a shallow phase of your sleep, youll be able to hear it and take control of your dream.
If you failed to achieve the state of lucid dreaming before, this simple app might just be the solution youre looking for.
