To me any way to RC is actually dream incubation. You are incubating the dream to be a lucid one when one of the criteria is met. But then there's the other part, the determining part..if the criteria is not met you are not dreaming...Y put that there? Might as well think of something that will trigger the dream of choice by itself. Like before you sleep during WBTB think of lucid related thoughts or go to lucid dreaming sites...it's more efficient than doing checks.
