When I was a boy (like 14 or so) I remember to become conscious while i was dreaming (not many times anyway, maybe just 3 or 4)... I never had the power/ability to control the scene but i remember it was very cool (I even told my mom)... I guess I could do that before because, as a boy, I had a lot of energy and my mind wake up when my body was sleeping... now, as an adult I barely can wake up with the alarm of my clock.
Anyway, I have faith it could be possible (with practice) to become aware while you are dreaming... In a sense it could be a sort of opposite of meditation in which your mind "fall asleep" while your body is awake.
Just guessing
