[Glenethor]

I think that is more artistic license, to a certain degree. She is able to look into the hearts and minds of others, and I believe that her Ring is responsible for that. I seem to remember Frodo (in the book) asking Galadriel why he could not perceive the thoughts of the other Ringbearers, and Galadriel replying that he had not really tried. However, nowhere in the book does she have telepathic conversations with anyone. She may project her thoughts, and read the thoughts of others (or, at least, that is what they say it <I>felt</I> like) but no telepathic conversations.
