Hi There Mystic Pilgrim, I'd be happy to point you to some good sources. "Lucid dreaming" is a broad term. I personally have found the academic and popular culture definitions to be quiet glib for the most part. The easiest blanket-statement kind of way to define "lucid dreaming" would be "conscious dreaming" or "dreaming consciously". With in that however there are many many different layers of perceptions.
One person's book that everyone who's done lucid dreaming and has read it recommends is
Stephen Laberge's book
Exploring the World of Lucid Dreaming. Dr. Laberge came out of Standford university who is one of the pioneering research centers for this type of work with
SRI & the Monroe Institute.
The
Monroe Institute is also a great resource on learning more techniques to lucid dream and achieve
Out of Body Experiences.
Robert Monroe is one of the few people who had the ability to "hop out" of his body at will from what some reports are. Here is a link to a great interview with Robert on youtube:
#1 Monroe's Out-of-Body (OBE) Paranormal Transformation of Human Consciousness
Lucid Dreaming & Out of Body experiences are very closely related as some would say they all take place on the "
Astral Plane" which again is a glib way of characterizing energetic transfer & existence for communication purposes.
Is there anything in particular you're interested in in terms of lucid dreaming?
