Dream of crowd, building

Walking toward dorm building. There's a crowd outside. I walk up to the crowd and notice it's dark inside. I ask a girl outside what's going on, and she says that some upgrade/new part of the building they're constructing has caused the power to go out somehow. I remark how "shit like this happens all the time here" or something like that. There's no one inside except one girl sitting on the couch, studying. Later on, I'm in a room on the ground floor, sitting on the bed. There's a girl outside playing guitar, who later moves just barely into my room, still playing the guitar. I'm impressed with her playing. Then she's sitting on the bed with me, still playing guitar. She says she's playing "Greek guitar" or something like that, and lists other styles she also plays.
