I've been lucid dreaming for almost 10 years, I routinely manipulated, move, destroy, and create anything I want. However in the past 2 weeks in many different lucid dreams I've felt compelled to take everything away and sit in the dark, and when everything is gone a triangular tablet glows as bright as the surface of the sun, it then typically draws me to it I just have to go, when I've stopped myself from moving it slides to me, this is often very strange as it grates like the sound you hear when stone moves over another stone in a movie. I have never been able to do anything to manipulate it. When I bodily reach for it I hear the words not yet a few times before waking up. I usually have one or two lucid dreams a night and this one particular dream happens almost daily now
