Are thought waves transmitted outside of the brain? and if so, are they received by the sub-conscious mind?

i had a philosophy teacher many years ago that believed that brain waves were infinite, just like sound, radio, water waves are, and they were capable of being received by the subconscious brain of other humans, he believed that some people were more able to receive these waves than others and that would explain people like savants who, though incapable of functioning on an intellectual level could sit down at a piano for example and play beethoven. It was an interesting theory and there is more to it, but i am wondering if anybody else has heard or thought about it..would this explain "deja vu"? in other words when deja vu occurs is it not something "we" experienced, but something somebody else did but we are seeing their experience with our subconscious minds?....
