That's the problem I've been having; staying calm. In the only four lucid dreams I've had I have been so utterly awed that I freeze up and can only look around and take in the scenery. Sometimes I've been able to observe certain things, or make small movements like looking at my hands or rolling on the ground and feeling pavement.

The first lucid experience I ever had I was in a arctic forrest doing something I normally do in dreams. I run for about 20 feet and leap into the air as far and as high as I can and end up doing a sort of hulk jump, but it's slow and graceful. I made one jump after finding myself in the forrest and realized, "Flying so is not possible..." I imeadiately became lucid and could no longer move because I was so shocked. I soared to the clouds and passed through them feeling a rush of cool breeze. I reached a point about 300 feet above the clouds and stopped. All I could do was look around at the mountain peaks wading in the clouds with the sun shinning very brightly on me. I could feel the wind one my skin moving my hairs. I began to question exactly how I became to be so on top of the world and withing 15 seconds I fell backwards and everything went silent. That's when I woke up.

Is this at all similar to the excitement you felt? It sounds like you had much much more control than I.
