My most vivid dream recently was school related... and it's weird...
This is the dream:
I'm student and I have a final exam, but I haven't studied. The form of the exam is essay. We have to complete a paper in class and turn it in.
Our school is a single-room igloo (in shape, it's not made of ice, it's a well constructed tent) with no real entrance for the students. There is a small hole on opposite "sides" of the tent (I realize there aren't sides on a circle). It's best to think of these holes as the entrance of an igloo, only smaller than for a human. Between the two holes is a well-worn dirt track. Walking head-to-tail, continuously, are turtles. They enter the classroom through one hole, walk down the path and leave through the other hole. To turn in your final exam paper you have to put your paper on the back of a passing turtle. The turtle with your paper on its back continues down the path until it exits through the hole. Just outside the tent are baby bears, which immediate eat the turtle and your final exam paper as the exam-carrying turtles exit the hole. That's how you turn in your final exam. It's completely normal and expected in this dream.
