Any time I have a lucid dream I wake up feeling more energized and awake than if I had just had a normal (unconscious) dream. That continuity of awareness from sleeping to waking state eliminates the need for me to reorient myself after waking from a dream.

There are times when I try to become lucid during the night, fail to do so but have woken up many times as a result. That can be pretty tiring the next day.
