I have had a couple lucid dreams in my lifttime, as I am sure everyone else has. Whether or not you would even remember to activate a book you would have to drill it into your mind the night before. It only feels like partial control, almost like you can control the dream with a brainwashed mind. I'm sure it gets better the more you do it though, unfortunantely lucid dreams rarely happen for me at least, never tried any of the lucid inducing products.
