Screaming or howling

This is one of my longer and more interesting dreams and my recall is waning by the second. Let us do this! This dream was either very long or was an extension of the previous dream (basically a DEILD without the lucidity). I do not remember the first parts, save for that my sister was involved and there was a show that I wanted to watch after school. Now to the parts I remember: I was sitting in English class. There was some trip you could go on that day. I am not one for doing after school things, so I refused. Besides, I had a show to watch. I said goodbye to my teacher and went to do whatever I had to do next. The school was not like my real one. After I was done with that, I had to hurry back to my English teacher's room, for whatever reason. The buses were leaving soon! I kept asking people how to get to her room, but the school was a bleeding labyrinth! I finally came across one of my friends and asked him, "What is the fastest way to Mrs. <PERSON>'s (my teacher) room?" He replied, "Well, you can go straight through... (this part eludes me) or you can go through Bavaria at either end of the school." In this dream, there were two regions we referred to as "Bavaria" at either end of the school. These places were locker/shower rooms bathed in piss where freaky German dudes hung out (no offense to German people). For whatever reason, I decided this was my only option. I moved as quickly as possibe through the piss-covered rooms, trying hard to avoid slipping and being caught by a German kid. I tried to used walls to retain my balance, but every surface was covered in piss! I was almost free, but the Germans came after me. As I was about to exit Bavaria, some girls screamed as they saw me (the area looked like a store) and some German tried to grab me. I suddenly became invisible to them and everything became grayscale and there were words at the bottom of my vision. This is where the dream ends. Again, I apologize to any offended Germans! *The fear of missing the bus is a common element in my dreams, but this is the first time it is happened in a while, possibly because school starts on Thursday.
