Which monologues to audition with?

I have an upcoming audition for a festival of short plays produced by a university (one that I graduated from last year). I am to prepare a monologue or possibly two, depending on time. I’m super stoked, but the only thing is that I’ve never auditioned for a play before (I did audition for a short film a few years ago), and haven’t seen or read too many so I’m not sure how to go about choosing a good monologue. If I had to prepare one, I feel like I should prepare a dramatic monologue over a comedic one.

Any suggestions?
