My recurring dream is that it's near the end of the second semester of my senior year of college, and I'm looking through some old papers and find my class schedule. While looking at it, I realize I'm still enrolled in a class that I haven't attended since the beginning of the semester. It's also a class I need to graduate. The rest of the dream is spent in a panic trying to contact the professor and find out if it's possible to salvage my grade.
Apparently it's an incredibly common post-college dream. I actually sort of lived it, but it wasn't a class for me, it was meeting with the graduation coordinator to ensure everything was good to go. I didn't meet with her until the last minute, and it was sort of up in the air until a day or two before graduation as to whether my name would get called.
