What if, you were having a great lucid one day and you pulled an unsuspecting DC off the streets. You gave him a very important responsibility, to remind you in all your other dreams that you were dreaming! Imagine, having a little helper to make you lucid, with no effort on your part! I haven't been able to test this idea out yet, since it would take a bit of time, but please, give me your thoughts or even try it out!
