Hi,
You should read Astral Dynamics. It answers your questions. Basically you have many different bodies. You're physical body, your subtle body (chakras etc), your real time body, your astral body, and then possibly an infinite number of bodies beyond that.
It's stated in the book that when you lucid dream you're in your subconscious and then become aware you're asleep in your physical mind which means your consciousness has not left your physical body. Now on the other hand when you project a mind split occurs and your consciousness shifts to a body outside of you physical and subtle body which never part from each other more than a few feet. Normally when this happens your realtime body or beyond inherits all of the memories from the physical brain and then starts recording info as a separate entity at this point and your physical body will know nothing of these memories unless your realtime body or beyond successfully downloads the new memories to your physical brain when you reintegrate with your physical body.
The difference here is that when you lucid dream you are still in your physical body "dreaming" and when you astral project you become a separate entity with it's own method of memory storage.
This is just a theory and be no means should you take my word for it and call it he truth because I doubt anyone that's around you really knows for sure. Read many different sources and ask many questions and have fun. Beware of people who tell you they know something as fact rather than opinion.
