What i dont understand is the ability to be able to do things... like walking for example and being able to fly. [/b]
what is it that you do not understand? in lucid dreams, you have a dream body. it is exactly like...you are now, you can feel, see, hear...think about it. you will feel exactly like you do right now in front of your monitor, only with the freedom to do whatever you desire. don't worry...once you have your first lucid dream, you'll understand. it is definitely worth the effort.

and just like Lowercase said, definitely check out the book Exploring the World of Lucid Dreaming by Stephen LaBerge.
