Exploring my mind

I was in a bus. Besides me there was the 11th class from school where I belong to. We were on the way to a boarding school and had to live there for three months. I was sitting in the front part of the bus, there were nine other pupils, and we were in charge of the bus. Then a teacher parked the bus and we got out. My room, which I had to share with somebody I haven't met before, had the number 695 and was on the fifth floor. I believe the building had eight floors in total.
Someone had told me rumors about the school, e.g. things were stolen out of the rooms, so I locked the room before I took a bath. While bathing my roommate told me that I had to go to a tennis lesson immidiately so I hurried up. Some pupils were already waiting before the room.
