As a researcher in psychology, I’ve approached this question scientifically. Despite the long history of lucid dreaming in human societies, it wasn’t until 1975 that researchers came up with an ingenious way to verify the phenomenon empirically. The first step was the insight that the muscles of the eyes are not paralysed during sleep, unlike the rest of the body. Inspired by the work of Celia Green, the British hypnotherapist Keith Hearne reasoned that this should allow lucid dreamers to communicate with the outside world. He had an experienced dreamer spend several nights in a sleep lab, and instructed him to flick his eyes left to right with pre-arranged signs when he finally entered a lucid dream. The volunteer succeeded, and Hearne was able to record the movements – which corresponded with the Rapid Eye Movement (REM) phase of sleep. Many later studies have since replicated these findings.
1. Set an alarm for five hours after you go to bed.
2. When the alarm sounds, try to remember a dream from just before you woke up. If you can’t, just recall any dream you had recently.
3. Lie in a comfortable position with the lights off and repeat the phrase: ‘Next time I’m dreaming, I will remember I’m dreaming.’ Do this silently in your mind. You need to put real meaning into the words and focus on your intention to remember.
4. Every time you repeat the phrase at step 3, imagine yourself back in the dream you recalled at step 2, and visualise yourself remembering that you are dreaming.
5. Repeat steps 3 and 4 until you either fall asleep or are sure that your intention to remember is set. This should be the last thing in your mind before falling asleep. If you find yourself repeatedly coming back to your intention to remember that you’re dreaming, that’s a good sign it’s firm in your mind.
