You've got an interesting point & concept - but if you really want to ramp things up, I've got two suggestions for you:
1. Tell folks to eat Stilton cheese a half hour before going to bed. If they've never experienced lucid dreaming, they're in for a treat.
2. Try 12-20 drops of mugwort essential oil at the base of the neck and just above the nose between the eyes, and below the nostril (men ONLY, or ladies with NO possibility of being pregnantk, as the essential oil is abortofascient, or can cause spontaneous abortions). It will cause the most incredible lucid dreaming a person has ever experienced. The oil is believed to open the third eye or a persons psychic mind. Nobody can say for sure...but what everybody knows is that it will introduce them to a level of dreaming and an awareness of their dreams that will change their lives!
