What you are suggesting is precognitive dreaming. I've had a few before about places I never been before but looks exactly the same in real life when I stumble onto it by accident. It is EXACTLY the same down to the blue tiling on the wall...I was appalled but the dreams there was no lucidity. I haven't tried places with lucid dreaming on purpose so I don't know if lucidity would interfere with the accuracy but I think it would because I tried to retrieve future information both lucid and non-lucid. The non-lucid dreams were accurate but not the lucid dreams but then again there was insufficient testing to really conclude anything concrete.
