I would just like to say that a very important DS i am having lately is about high school friends. As i donīt see them often in WL, i RC everytime i think about them, as you suggest, and also, as a way to RC, i try to find them in my surroundings.
What i am suggesting is that a DS may be not only a reminder to RC, but also the RC itself. For instance, in my nLDs i usually fly, but somewhat misteriously i donīt get lucid. So, i decided to try to fly as one of my RCs. And by now i have found my self flying a couple of times
