Luxenburg?

In my dream I was a small boy of about eight. My parents and I were running from someone. We thought we'd have a better chance if we split up. We had to get to Luxenburg. I went the wrong way on the stairs and missed the train. For some reason I had to give my wallet to a chubby black man in order to get to the bus. When I got to the bus I realized I had no money so I tried to bow my head and get by the driver. She was going to let me on anyway because she saw my train ticket but I had to show my driver's licence. I went back inside to get my wallet. There were hundreds of identically dressed people in chairs facing forward. The black man was among them. He mimed that I needed my wallet. I nodded and he got it for me. When I got back to the bus there was a tv screen on the side of it that said there was a plague emergency that the bus had to respond to. It started to leave without me. I jumped on the side of the bus and held on. Eventually the bus driver stopped and let me in. By this time I was myself.

Some odd things about this dream:

• To my knowledge, I have never dreamt I was someone else before. I didn't recognize the eight-year-old or his parents.
• What eight-year-old has a drivers licence? This seemed perfectly normal in my dream and became a non-issue since by the time it got time to show my licence I was myself (though even when I was the eight-year-old the wallet I recognized as my own).
• I know nothing about Luxenburg other than it must be somewhere in Europe (because of the German sounding name). I have no idea why I would dream that I needed to get there. I looked it up on the net just now, though, and some info can be found here.
• Somethings seemed normal to me that should have been weird: What's with the identically dressed people? Why would a bus need to respond to a plague?
