It's a fascinating subject for sure. I dream every night and have some amazing detailed dreams, but I have yet to be lucid in one. There are a ton of books on the subject and the one I'm currently reading is Dreams of Awakening by Charles Morley. About half-way through and it's a great read.

Not only about lucid dreaming but also being lucid in 'real life'. How to wake up to the unreality of it all.
