This is a book by Castaneda I've read several times over with great interest over the last 5 years, and it contains some of the most provocative and frightening information about the high art of dream travel that I have yet to encounter. It is not for those that don't want ALL the knowledge available, and it is not for the faint of heart.
It encompasses an area that I strongly believe, and that I feel is all but left entirely out of most LD discussion: the worlds that we create and experience ARE REAL.

(I strongly advise that you find and read "The Teachings of Don Juan: A Yaqui Indian Way of Knowledge" before tackling this, but if you're open enough, you should pick up pretty quick)

The Art of Dreaming

Good luck on your journeys, and safe travels.
