I walk into a room and it is my highschool English class. My PhD adviser is taking the class. He scowls at me angrily and asks why I am late to class. He then tells me that the exam I have to sit is on later that day. I haven't prepared for it. He says something sarcastically about how he has as much confidence of me being prepared for the exam as he has for me publishing my research.
I wake up in cold sweat.
