This is good exploration of the subject. When I was younger I remember controlling my dreams a few times. Sometimes the dreams involved flight or just becoming aware that my situation was surreal, although I never seem to fully realize "I am dreaming" when I am. It's only just a subtle feeling when it happens. And more often than not now I do not dream, or at least I do not recall my dreams. Once and a while I do and hold on to usually a singular vivid impression for around 45 minutes after waking, and then disappears.
