I think it's very possible to have dreamed of a place you've never seen. It somewhat frustrates me how people who are so into dreams are such skeptics about the possibilities beyond the usual. So many people have precognitive, psychic dreams and i think the brain is in the perfect state to receive such information when dreaming.

I had similar dreams a couple months ago. I saw an exit and a street name...looked it up and verified. I also dreamed of a street name along a school campus...looked it up on google and there it was. I've never been to either place or seen them in real life.
