Then there was another one earlier this morning, involving this big "0" shaped racetrack type thing, that all these huge circular vehicles were on. Each one was the width of the "track", divided into (I want to say) 8 equal sections, where each section had a guy with a light inside. Presumably it was some sort of construction plant or something, but said vehicles would run the length of the track, slowly rotating, so the men inside could inspect the track and other such things for problems. They presumably finally finished that though, because suddenly I was up on the roof with a bunch of other men and women. Except the "roof" was like a smooth asphalt driveway or whatever's similar to that. Some lady was there too that seemed to be the one in charge, and started flipping through some book, looking for something, and I started thinking we were going to sing.
Dreams are weird :s
