Tried this last night and it was a complete success, somewhat to my amazement.

I was walking through a hallway, going to my office. Suddenly I realized that I might have been sleeping, and had just told myself I was going to have a lucid dream. For the first time ever, I voluntarily looked at my hands (the only other time I used this RC was when I happened to see someone else' hands in a dream). Sure enough, they were a little deformed.

I will try to repeat this tonight, and see what happens. I have never yet had a lucid dream two nights in a row (once every week or two is about the best I have done), but I'm curious to see what there is to this.
