This game is designed to heighten awareness of the world around you. It does this by removing the visual input to the brain and so forcing it to evaluate the current situation using the only senses available to it; those of hearing, smell, touch and thought.
The starting point of creative journaling is learning to be aware, to actively pay attention to what your senses are telling you. The next stage is to learn how your perceptions are modified by your mind, and be active, not passive, in those perceptions. Finally, make use of these skills to be properly aware of the world that surrounds you.
