I did that once. Stayed up all night doing an essay then drove to work at 7am to drop it in before the lecturer came in and checked the drop-in box. On the way a huge spider climbed out from behind the sun visor, and I flicked it off, then flicked it out the door.
I dunno... may have been real, but I think it was an hallucination, mainly because five seconds before it appeared I thought about how fucked it would be for a spider to be behind the visor.
