I was in my elementary school cafeteria talking to a friend from middle school/high school. For some reason he was singing African folk songs, which was weird, but he is a music major so I guess it's not completely strange. Everyone else in the room was mimicking what he said. I didn't find this strange in the dream, it seemed almost like a joke, but thinking about it now it was kind of bizarre. I'm also not sure why people from my high school were in my elementary school as they are in different school districts.
