Ahh lucid dreaming. I too have experimented with this over a year or two, and my very first intentional lucid dream started as a falling dream. I remember standing on top of a cliff, looking down and seeing the tops of pine trees. It was a forest of pinetrees. I fell of the cliff face first, and was falling into a clearing. Instead of falling and waking up as i came to the ground, i pulled up and found myself to be flying. Thats about all I can remember of the dream though
