"In I Remember, whenever we were handed something, we were to say 'I remember', or acknowledge the action in some visibly apparent way... The Doors of Perception required that we touch each doorframe as we passed through... At this point, a provocative question was posed: Could we be dreaming at that very moment? ...Stephen stressed the importance of making reality testing habitual and encouraged us to keep a vigilant eye out for dream-like events in waking life which would help prepare us to recognize the anomalies in our dreams." --Diary from Lucid Dream Camp
