Hey Rickey, that research sounds very interesting. I beleive that some very preliminary studies may have already been done on that (though I do not know how rigorous they were) - I definitely have read of one author comparing muscle memory between a. people who physically practiced an activity, b. those who imagined that activity, and c. those who practiced in a dream state. Don't quote me on it, but I think the test was throwing a basket ball.

I see no reason why this couldn't be tested. The hard part will be getting a bunch of lucid dreamers in a controlled setting.
