Thanks so much to both of you for your help!

To answer the question, I do get a bit excited but not manically over-the-moon. I'm not sure if this is because I am not actually lucid or just that I have a tendency to keep calm. I've had lucid dreams in the past (before I knew what they were) in which I was 100% aware that it was a dream and this doesn't seem entirely like that experience.

I had another LD experience last night, my third in the past week. To summaries, I was at McDonalds looking out the window down on some buildings. I noticed they were kinda 2D and flat, like post cards. I did the finger LD, and noticed that my ring finger was tiny. I began rubbing my hands together (per RebelSeven's advice ) and left the store. Once outside I did another RC (my fingers were still messed up) and actually asked myself where I had been before I was at McDonalds. I can't really remember my own answer though.

I attempted to fly, and managed to soar up about 50m in the air which was pretty cool. I got up to the height of this big lamp-post, after which I couldn't really get any higher. I attempted a headfirst dive towards the ground, but at the bottom of the dive when I tried to head back up again I couldn't and woke up.

I'm not sure whether I was technically lucid or just dreaming about having a lucid dream. But last night the thing lasted much longer than the previous 3 encounters (perhaps due to the hand rubbing thing) so I feel I must be on the right track!
