I've had several experiences with lucid dreaming. I found that once I put my mind to it, it really was rather easy to achieve, although I did lapse into dream consciousness after a few minutes. Funny how it works, that even tho you are aware that you are lucid dreaming, you can get so caught up in the dream itself that you foget it is a dream.
My first dream started out pretty simple: I was standing at the edge of a field and saw a fox come into the field. It occurred to me that this was a dream and I could do whatever I wanted, so I took a perspective about 50' overhead and continued to watch the foxx. Then it occurred to me that since it was in fact MY dream, I didn't have to settle for watching a fox, and the next thing I knew I was at a party in my old franternity house. After a few seconds I started to lapse into the dream, but when I saw someone from my current life there again realized it was a dream. So I thought I would bring in someone famous, but couldn't really decide who, and while I was considering the question, the "six miollion dollar" woman appeared (still can't remember her name), which I remember thinking was an odd choice, and so she walked over to talk to me, and the whole thing felt pretty weird and I thought I would try and think of someone more interesting, but got caught up in the dream at that point and lost my lucidity.
I've had several other experiences, but the flow seems to be the same in terms of lapsing in and out of awareness and finding that the dream moves in the direction that I want, but also in a way which sometimes surprises me
