Failing School and Scary Animals

I keep having dreams about forgetting to go to class and failing. Last night I was in college and taking 3 classes, 2 of which I were getting F's in. I planned to stay up all night cramming for the exam in one of them to at least pass the class. And I was upset because I was failing 2/3 of my classes, so why bother paying for all this school? *

Also there were scary animals - kind of like eels. I kept capturing them and trying to kill them, but they would divide and wriggle away. I've had lots of scary animal dreams, especially about fish (since recently aquiring a pet goldfish).

*I've been done with school for 4 years. When will I stop dreaming about it?
