Hello everybody. I have some questions.

Let's say I want to learn how to play Guitar or learn a language like Spanish. Is it possible to learn or "activate" it in a lucid dream?

I also remember reading something on modifying yourself. How is that and has anyone ever researched that? And what about to the extent of modifying how your hair grows and other psyhical(sp) elements?

Thanks in Advance, I'll be back tomorrow after school to see your responses.
