carlos castaneda

this is a quote from a carlos Castaneda book. I wanted to know if anyone has tried this before while dreaming.

"The position in which one places the body is of utmost importance. Start your dreaming by lying on your right side, with your knees a bit bent. The discipline is to maintain that position and fall asleep in it. In dreaming, then, the exercise is to dream that you lie down in exactly the same position and fall asleep again. It makes the assemblage point stay put, and I mean really stay put, in whatever position it is at the instant of that second falling asleep. The result of this exercise is total perception. The four variations of the exercise are to fall asleep lying on the right side, the left, the back, and the stomach. Then in dreaming the exercise is to dream of falling asleep a second time in the same position as the dreaming had been started."
