tihs dream was odd. i dreamt i was driving a bus in Japan, which was very confusing, due to the fact that it was an American bus, but the Japanese drive on the left side of the road. my former Japanese teacher was on the bus, yelling out instructions to me. i tried to comply, but i kept missing turns and getting cut off because i didn't know what i was doing. the passengers on the bus were getting mad at me. also, there were a lot of roundabout intersections (i don't think Japan actually has these), and i had no idea how to drive though them, so it took forever to get anywhere. eventually i gave up and told someone else to drive the bus.
possible explanations: i recently had a conversation about left-right driving in various countries.
