The app will indicate if you are just dreaming or in reality.

If you want to try to learn clear dreams, one possibility is to ask yourself during the day time and again whether you are dreaming or awake. This is called reality checks. The point is that you get so used to making these reality checks in a dream. But the dreamed environment usually reacts differently to these checks and you realize that you are in a dream.

Then you can design the dream at your own discretion.
