$19 Bill

So I had a weird dream last night. I was trying on my old band uniform. (that's right, I was in band. Wanna fight about it?) and I found a whole bunch of money in the pockets. My real uniform in high school didn't have pockets, but my dream uniform did. Anyway, I pulled out a couple 20s, a ten, two ones and a freakin' $19 bill. What does that mean?
