There is a significant recreational benefit. Flying feels amazing, and while I don't lucid dream anymore due to THC supplements for sleeping, I remember being fascinated and endlessly entertained by how _real_ it felt. I also remember quickly waking up upon the exciting realization that I'm dreaming. Rubbing hands together to stabilize the dream as you feel it slipping is a strategy I remember using. Or skipping inadvertently back into that gullible state where you take the most outlandish stuff at face value and outright forget that you're dreaming.

Pretty amazing when is works, though
