Exploring The World of Lucid Dreaming

By the same token, you can practice new skills in lucid dreams. In Exploring The World of Lucid Dreaming by Dr Stephen
LaBerge, a lucid dreaming surgeon explains how he would review his surgical cases for the next day before going to sleep.
Then he would practice them in precise detail in his lucid dreams – he had a solid reputation as a surgeon because of this,
being able to refine and polish his techniques and perform procedures much faster than average. Similarly, lucid dreaming
has been shown to improve the procedural memory of your muscles, so you can practice martial arts or piano playing while l
ucid, and you will be physically better at it when you wake up.- source:Lucid Dreaming – Waking Up to Alternate Realities , by Rebecca Turner from: evolution ezine
