I have been wondering about this for some time now but I haven't been able to find any information on the matter so I thought i would ask here.
Is it possible to practice/train/learn stuff inside a lucid dream and then apply it to real life.
Jiu-jitsu is just an example and a catchy headline. I have also thought about rehearsing speeches for school etc.
I have not had a lucid dream yet so unfortunatly I can't try for myself.
I hope someone's got a clarifying answer for me!

By the way i realize that Jie'jitsu would require physical training aswell. Not only for strength an stamina but also for you body to actually learn the moves (nerve endings etc.) but I think you get the idea of my question
