Failure(?)

For a while not, I've had a recurring if infrequent dream. It revolves around me being at university, though my attendance has been poor and it's exam time. My lecturers are looking for me, for some... I can't figure out what it is - my exam papers? Coursework? It's definitely something along those lines. I'm at risk of failing, though I can't understand why. And before I get any answers or before my lecturers find me, I wake up in a somewhat anxious mood.
