Weird/Disturbing Dream

I guess stress manifests itself differently in my life. Yesterday night, it was in the form of a really weird/almost too realistic dream. What did I dream about?
Well, the first scene I remember is me oversleeping for my flute lesson. I woke up and looked at my cell phone and found that Emily had left me a message. She basically called me and said “I know you overslept [first of all, HOW did she know? lol], and I have many students to teach tonight, but if you can PLEASE, PLEASE, PLEASE call me back ASAP, I can maybe squeeze you in sometime tonight.” I looked at my phone, and I was going to call her back, when I was suddenly transported to school. At school, I see Dr. Coletta walking down the hallway, and she gives me this “i’m disappointed in you” type of look. I was going to rehearse with flute choir, when she stops me and asks, “How many minutes do you have left?” (regarding time for the music lab) I respond “I don’t know…. like 13 minutes or something like that…”
And then I woke up , panting and screaming, because I had to get ready to leave in < half an hour for the flute choir performance at concert hour this morning. Blegh.
Worst fear = oversleeping for my flute lesson
Realistic/Disturbing aspect = Dr. C. asking about my lab minutes. EWW.
