Lucid Dreaming

Has anyone looked into or tried lucid dreaming/meditation? If you don't know or remember what lucid dreaming is it's the act of becoming conscious that you are dreaming. Most people do fun stuff like fly or have awesome sex with some dream girl, but there are cases I found online that claimed that they healed themselves in their dreams. They go as far as claiming that dreaming of healing another can even possibly have effects on them. I am currently in the process of becoming a lucid dreamer, and was just curious if anyone has tried it. There is a forum on here about lucid dreaming but nothing pops up in this forum about it.
