What we do know for sure about the Three-Eyed Raven is that he is a Greenseer, gifted with the ability to see the past, present, and future and communicate through dreams. Greensight is more common with the Children of the Forest, but some humans, like the Three-Eyed Raven, also have this ability.
While he appeared to Bran as early as Season 1 in the form of an actual raven with three eyes, it wasn't until much later that fans got a glimpse of the Three-Eyed Raven in the flesh. When Bran traveled north of the Wall, he found the Three-Eyed Raven living in his hideaway, a cave beneath a massive weirwood tree.
