Suppose it happens. You rise and float, or a dream suddenly becomes clear. What then?
The first moments are often unstable. Colors flicker, the scene wobbles, and the excitement itself can pull you back into your body. Old dreamers used a simple anchor: your hands. Look at them. Then glance at four other things around you, briefly, without staring. Return to your hands. Each return steadies you.
Move away from your sleeping body. Staying close to it can draw you straight back in.
Then do one thing, not ten. Take one step, look up at the sky, or ask one question. When things begin to slip, go back to your hands and begin again.
If getting out is the hard part, there are other simple ways through the door. Intend to roll over, as you would roll out of bed, without moving a muscle. Or let yourself float upward. Or picture a rope above you and pull yourself up it with your hands.
Coming back is never a problem. Think of your body, and you are in it. Nobody has ever failed to return.
Then, before you move, go through it all once in your mind, and write it down.
