It was primarily created as a form of Dream Initiated Lucid Dreams, which involves setting an intention to recognize the dreamstate (as a form of self-affirmation) by telling yourself to look for dream signs and performing Reality Checks throughout the waking day.
The next stage involves placing your intent to lucid dream. While returning to sleep, concentrate on your intention to recognize that you're dreaming. Repeat "Next time I'm dreaming, I will remember I'm dreaming," like a mantra. Meditation helps master your focus during this state.
Finally, imagine you are back in the dream world and look for a dreamsign - some cue that you must be dreaming. Relate it to your reality check if possible. For instance, try floating in the air. This may also be your lucid dream intention and is a good way to program your next dream in advance.
Because it is easy to master (almost everyone sets intentions frequently), it is ideal for research purposes involving subjects who have never practised lucid dreaming induction techniques before.
