Hi!
I recently read article about brain activity and stuff where this guy had lost his left arm. So these scientists connected those brain wires left loose ment to move his arm to electric wires so that he could move a pointer (after while practising) in a computer screen. This of course gives us people all kind of possibilities to build up stuff in the future and one of them could be writing, while dreaming… What you think? Or have this already happened, dunno.
Maybe i can work with these kind of things someday…
