A lucid dream is a dream in which the dreamer is aware of the fact that they are dreaming. While lucid dreaming a dreamer can alter their surroundings and control their dreams. Lucid dreaming allows you to do whatever you want - in a world that you control.
One of the most effective ways to trigger a lucid dream is by performing reality checks during the day. A reality check is when you periodically stop what you are doing throughout your day & truly question whether you are dreaming or awake. The theory is that the more you make reality checking a habit, the more often you will do it in a dream, and you will turn a regular dream into a lucid dream.
Reality Checks: Lucid Dreaming is an application that will let you schedule notifications at an interval that will remind you to perform a reality check. This app can be integrated with any current lucid dreaming technique in order to increase the odds that you trigger a lucid dream.
Simply set a start time, an end time, and a frequency, and you will be automatically prompted with a reminder at each interval.
