That was Sensei who liked lucid dreaming to a sport. Although, lucid dreaming doesn't require the physical exertion which defines a sport.

Actually, now that I think about it, the lucky people are they ones who unconsciously adopted a lucid lifestyle before getting into lucid dreaming. They have a much easier time with lucid dreaming than those that don't because of their head start. Also, those that naturally have many false awakenings such as myself will also have an easier time due to the tendency to heightened awareness in those dreams. Having false awakenings is luck. I'm lucky and grateful!
