I remember a thread a couple years back about healing yourself in a lucid dream, but I can't seem to find it. The sub-forum Beyond Dreaming has a lot of people who look deeper into lucid dremaing, discussing things such as OBEs (Out of Body Experiences) and even dream healing. I suggest you search around for a little bit and if you have more questions, go ahead and start a thread. The topics can get a little controversial, but that typically stays in the deep dreaming subforum, where you need permissions to access. The beyond dreaming section should be very helpful to you though .
