Please NO MYSTICAL STUFF in this thread. Thank you.

Hey everyone
I keep reading in topics about people talking about OBE as if it's something entirely different from lucid dreaming, as if you can practice for having OBEs and Lucid Dreams seperately.
From what I thought (I have no clue if I'm right, which is the reason I'm creating this topic) OBE was a lucid dream where you could fly around and see your body lying down there. If so, it's a lucid dream like any other right?
