Lucid dreaming on cue is an acquired specialty. The most important thing you can bring to lucid dreaming is the understanding that the phenomena is real. If you think it is all BS you will not succeed. I know it is real. I have been there. I have felt the cold and rough concrete walls in a LD and been amazed. I have smelled the musk of a llama in a LD. It was as real as I feel typing this. I have strolled through brunt out cities, flown incredible journeys, and done the things only Greek Gods could have done. Lucid dreaming is altered reality that only enlightened humans can appreciate. To anyone who has not had a lucid dream I can only say this... believe it. You have not died... but you will. Lucid dreams are the closest thing to the heavens showing us what death is. Once you have a lucid dream... a real lucid dream... you will lose all fear of death. This freedom will allow you to do incredible things in your life. Good luck to you!
