I'd say it's dejavu in a dream, but not necessarily lucidity. Were you aware of yourself?

Check this out:

I've dreamt lucidly of a particular tower in the dream world, spent some time flying around it, drawn a picture of it, and when my girlfriend saw the picture, she said, "I had a dream of that tower when I was a kid! How did you know?"

I highly doubt the two of us had any common experience in childhood that could have made that happen, my girlfriend is from Taiwan and I'm from Alaska. Also, the tower was designed in a unique way that only lucid dreamers could get inside. When I saw it, I knew it was built specifically for that purpose.

Now, my mission is to prove that there are indeed common places in the dream world that dreamers can visit. I've had similar experiences on more than one occasion, so I'm sure it's true, I just need more evidence at the moment.

Anyone else have this experience?
