I think it can, as, as TLS said, nerve paths are better developed. For sure, you can't gain muscle mass through dreaming, so don't think that.

Nerve paths can be heavily increased, and I don't just mean for skateboarding. Doing math equations in dreams is the same as real life. Most things you do can help you.
Actually, this symptom is named in a few books, including Exploring The World of Lucid Dreaming. I'm sure it can be done.
