I haven't read anything recently on this subject. I read most of his books years ago as they were published. Castaneda's works always left me feeling curious about how everything was put together in the universe and how it was all supposed to work. I am a geophysicist by training so I have a good exposure to science - enough to know that there is a lot more to learn. I haven't delved deeply into any lucid dreaming or similar subject matter. I wish I could be more help.
