Dream of hands, toilet, number, mother

I Went to school starting the new semester. I had trouble finding my classroom. On my schedule it showed a number that didn't make sense, but when I showed someone else to get help it showed the right number to the classroom I needed. While in class I was goofing around with two guys I don't really talk to and there was a girl I haven't even seen since elementary school. My sister was suddenly behind me telling me to stop flirting with other guys because I was already "engaged". I asked the teacher to go to the bathroom. I went to the one right beside the classroom which I'd never been in. When I opened the door it was disgusting. It was made of old, dark wood and straw covered the floor. Everything was brown and covered in maggot and other small bugs. I was afraid to sit on the toilet but I did anyway, I could feel the bugs trying to crawl on my legs. I had to per but I couldn't seem to do it. I tried to quickly finish then went to the sink. It was long and deep, there was clothing stuffed in it and when I moved them, water was pouring out of the faucet. I realized it was broken. I washed my hands. Luckily there was soap. I took the clothes and tried stuffing them back in the faucet to stop it from running but I couldn't get it quite right but I wasn't worried. I left in a hurry and started walking down the halls of school where I found my mother.
