Faramir's (and Boromir's) Dream

[Nerwen]

The dream was sent by an anonymus person, and probably fate. But I think that in LotR fate hardy does anything by accident. I think that this time fate (in the face of Eru, who planned out all the events of the world up to the very end) chose Galadriel to act through. Galadriel has her "magical" mirror, through which she can see the future. She also has a gift of telepathy, which means that can speak using just her thought, not her actual voice. I think that Fate, or Eru made her want to find out a little bit about the future. Galadriel decided that she is the one who is destined to push one of Denethor's sons to come to Rivendell, so she sent the dream and spoke in it. She is wise enough not to blurt out everything, which would turn Denny against the mission of destroying the Ring, because he would want the Ring hinself.

Sorry, but this is just another way of saying, "Galadriel sent it". Which I think is most unlikely, for reasons already stated.

And also, if the dream had been sent by one of the characters, I believe there'd be some hint of this somewhere, and there isn't.
