I'm glad you were able to maintain that this is very likely coincidental. I had a lucid dream, in which I was walking down the street where I lived. As I walked, I passed a red truck and a blonde woman inside the truck put her hand on the glass and startled me awake. Several months later, I split up with my ex and the only vehicle I could afford was an old red truck. Later on I began seeing someone (a blonde) and one day as we were driving, I looked over and it just clicked; the truck the blonde... Whoa.

I think there are a lot of factors at play; coincidence, self-fulfilling prophecies, false memories, deja vu (or deja reve), people's inability to remember dreams clearly in general, their propensity for remembering this differently than they were, etc. Still, very interesting stuff.
