Dream Within a Dream

Last night I began my dreaming as a student who was attending a sort of blend between college and high school, and I was the last pick for the orchestra, but I was in. So everyone was getting to know each other when all of a sudden the director came out of his office and told everyone we had an hour to practice before chair placement auditions and then handed us the music. Everyone panicked and went to different classrooms to practice. I was freaking out and also went into a room to practice, but it took me forever to find a room. After playing a few notes I realized my violin sounded terrible. Then I went to find the director to tune it, and on the way there I broke my violin bow. At that point I "woke up" (in my dream still) and I was surrounded by the orchestra. I told them about my dream and they laughed.
At some later point in the dream I had to submit a proposal for a science project. Everyone's proposal was great except for mine, because I had forgotten to use some weird physics equation which was essential to the project. So the teacher asked me to do it again. I went off to the library and I cried in frustration. Then I remember focusing very hard on the equation and what it was talking about, and I figured out a new proposal, and went back and turned it in to my teacher.
Additionally, I had another dream during the night where I rode around in a homemade vehicle, and I had to find my brother somewhere in the city, and I ran into my cousins.
