So when I tell myself to wake up after each dream, I recently figured out that I'm actually waking up in between REM and deep sleep cycles. And for some reason I figured that when I woke up, the next cycle would be deep sleep. So my question is, is it possible to wake up right before a REM cycle using autosuggestion? And also, is it possible to use autosuggestion to wake up after each dream and not just in between cycles?
