toilet fish

I dreamed I decided to use a toilet as an aquarium and tossed a bunch of live fish in one. My boss advised me to add a water heater to it, so I did so and also added an aquarium filtration system. I was also starting college at a DC area university. I went to a class and had a professor who was verbally abusive to everyone. I decided I would rather stand towards the front of the room instead of taking a seat, and he yelled at me about it. He also yelled when I asked if he had a syllabus for us. I left class angry and ran into three or four of my real-life co-workers in the building.
