Things that have worked for me in the past; when I am LD'ing and may not like the way things are going, or I want to repeat a scene that was fun,pleasurable,or interesting, I give a command; e.g. 'stop', 'repeat/rewind', or my favorite to do, 'switch scene'. It always works for me. It extends the dream or allows multiple themes within the dream. I think it and it becomes so. If, while LD'ing, I become aware of a physical stimulus affecting my body in reality, I simply command, 'wake up' and I'm awake. Relax and go with the flow. Your brain wants to help you. Think it and it will happen. Enjoy the movie!!! We'll talk later.
