The first time I had a ucid dream it happened unvoluntarily even know I had a habit every since I was a child to listen to a natural high pitch tone of the mind I let my ears go free. Then your feet are important for drawing energy, but don't draw to much it can be to much for comfort. Fall asleep to these pitches don't concentrate. After a few days it becomes manditory and like me you could fall into a deep lucid dream unvoluntarily. The best time for me to have lucid dreams is in Fall and Winter. My favorite season is Winter.
