Going to School in Your Underwear--Huh?

So, I started my new job a couple weeks ago (and it is a great job, btw), but the night before my first day, I had one of those dreams. Yes, one of those. Crazy thing about it? I have never had one of those "gone to school in my underwear" dreams before. I guess I was really nervious about that first day!!! Now, I know what they mean about those dreams.
