Sounds like in the OP you were aware that you were dreaming, but not in control? This is pretty common. Sounds like you were in the lowest level of lucidity. There are many levels of lucidity ranging anywhere from thinking that it could possibly be a dream but not being sure and lacking control. All the way to being so aware of your state you can even think about waking life and you can change the dream however you please. It takes a lot of practice to get to the upper levels of lucidity, most beginners have trouble being completely in control of their actions. I had a lucid early on that I couldn't walk straight. I was forced to wander around the dream like a drunkard
Sounds like in your last post you were in control of yourself though, grats! It will only get easier from here!
