Nightmares about the first day

I don't know if this is normal for teachers before the first day of school...

but I have been having nightmares about the first day! Please read my ridiculous nightmare that I had last night..

It's the first day of school for students and my first day. I am wandering around the school building lost and trying to find my classroom. The bell rings and I am LATE to my own class. Finally, I find my room and it is NOT a science room. All of my students are waiting for me. I try to figure out how to hook up my computer to the projector and while I am doing this all of the students are running around the classroom going crazy. They are climbing in and out of windows, throwing things, and students are crowd surfing. The assistant principal walks into my room and gives me a video I should show since I am obviously not prepared. So I pop in the video and none of my students are watching it. I try to get the class under control but no one is listening to me. Finally, I step out of my classroom and the teacher next door to me starts yelling at me that I am a failure since I can't get them under control.

and then I woke up!

I am getting very little sleep now a days because I am anticipating what my new school is going to be like. AHHHHHH!!!
