Too short to make sense?

Following the theme of school and teaching, my dream took place at a university with beige buildings, where I witnessed an overweight man being shot, who I assumed to be a professor. The students around him quickly ran away while saying "Its ok, he wasn't a good teacher anyway", to which I was horrified to hear. I suddenly found myself driving away on a freeway that was going no where in particular. And then I woke up thinking, I hope this doesn't relate to the class I will be teaching in 2 weeks.
