I've seen a scattered few articles on the idea of lucid dreaming for practicing a skill, like music. Presumably this should be possible with any skill (within reason) that requires muscle memory. But I've noticed even when my dreams feel pretty realistic, if I practice rolling (martial arts roll, not gymnastic), the impact isn't the same as it is in reality. I'm a fairly inexperienced lucid dreamer as far as intent to LD goes, and I'm interested in your opinions. Could one conceivably practice music, martial arts, dance routines, or anything else? What about beyond practicing, but actually learning new skills, like teaching yourself to do a backflip?
