Ah. As far as I know, lucid dreaming does not really affect your sleep, since you are still fully engaged in a full sleep state. Sometimes, the things you do in a lucid dream will affect your "satisifaction" of sleep.

Like.. when you wake up from a nightmare, you are uneasy, and don't really enjoy your night. But, if you have a dream about your crush or your favorite hobby.. things are different.
