Missed Class

This is a recurring dream I have.  I'll be at school, toward the end of the semester, and realize that I have not gone to a required class the entire semester.  I start freaking out, wondering if there's any way I can make up all the work and cram for the final exam that starts in ten minutes.  It's futile.  I even go to the final, hoping I can guess a few right answers.  I get so anxious in these dreams.
