As a kid, I was so happy to "discover" that I could be mildly awake and control my dreams. It happened by mistake: I fell asleep while listening to loud music. I was in a middle state, half-awake because of the loud music, and half-asleep, dreaming. In the dream, I was an observer, aware that it was a dream. The music in the background was annoying me, and it was stressful. Later, I "improved" the technique and learned to control the dream while blocking out the annoying music.
