The Impossible Movement Practice - how often to do the movements?

@Jindřich Pelhřimovský It is called "impossible movement" because you imagine a movement that would not actually be physically possible at the moment if you tried it for real. Like making a fist if your head is resting on your hand that is spread out flat. Yes, it is possible to imagine this movement but not possible to physically do it, and that's exactly the point! You keep on imagining it, repeatedly, and when it suddenly feels like you're actually physically doing it, you know that you have crossed over from the waking to the dreaming state. If you imagined a movement that was possible to do, you would not be able to reliably tell if you are already asleep or still awake. And no, you are not supposed to try to do the movement physically, just imagine it until it feels real!
