I'm at a University. The building is huge and complex, but I seem to know my way. I'm leaving but remember that I have no coffee at home and decide to find a place to by some. There's one inside the university building, so I turn back and try to find it. I take stairs up and they turn out to be winding stairs that go to the top of a tower. No coffee there, but I find myself at the reception of a doctors office. I'm at the doctors office, a nurse is checking my knees. There is some blood on them, but I think it's actually about the joints wearing down. She wants to run some tests and needs to take some blood. I'm not worried but there is a change I might need surgery.
