The MILD technique employs prospective memory, remembering to do something (notice you're dreaming) in the future. Dr. LaBerge developed this technique for his doctoral dissertation and used it to achieve lucid dreaming at will. The proper time to practice MILD is after awakening from a dream, before returning to sleep. (Modified from EWLD, p. 78)
Setup dream recall.
Set your mind to awaken from dreams and recall them. When you awaken from a dream, recall it as completely as you can.
While returning to sleep, concentrate single-mindedly on your intention to remember to recognize that you're dreaming. Tell yourself: "Next time I'm dreaming, I will remember I'm dreaming," repeatedly, like a mantra. Put real meaning into the words and focus on this idea alone.If you find yourself thinking about anything else, let it go and bring your mind back to your intention. As you continue to focus on your intention to remember when you're dreaming, imagine that you are back in the dream from which you just awakened (or another one you have had recently if you didn't remember a dream on awakening). Imagine that this time you recognize that you are dreaming. Look for a dreamsign--something in the dream that demonstrates plainly that it is a dream. When you see it say to yourself: "I'm dreaming!" and continue your fantasy. Imagine yourself carrying out your plans for your next lucid dream. For example, if you want to fly in your lucid dream, imagine yourself flying after you come to the point in your fantasy when you become lucid. Repeat steps 2 and 3 until either you fall asleep or are sure that your intention is set. If, while falling asleep, you find yourself thinking of anything else, repeat the procedure so that the last thing in your mind before falling asleep is your intention to remember to recognize the next time you are dreaming.
