Hmm... that feeling that there is more to life than the daily drudge, or that you can do things you've always wanted to but can't for whatever reason or are impossible. I rarely get to do the things I really enjoy, and after waking from a lucid dream life just seems like there is no way it could get better. And when I say lucid dream, I say waking up upon realizing you are in a dream. I can't imagine how wonderful it will be once I can actually have them frequently with some element of control! Not to mention introspection, and communicating with your own subconscious just sounds way cool

Plus I have heard that it is a good way to practice things in real life. If I can spend my dreams rehearsing for things (like my upcoming presentation for class), that would be a very good way to spend the 6+ hours I spend asleep (i realize this probably needs to change to actually achieve LDing often)
