Recurring Dreams

Sometimes I dream I'm back in school. Usually it's high school or college but it's never like it was in that the campuses are always larger, spread out over a wide area and often the buildings are twisty and Escher-like. I'm either trying to get to class and can't find my way or I've lost my schedule and don't know where I'm supposed to be or I've forgotten the combination to my locker and can't get my books. It isn't scary, but rather like when you forget to set your alarm clock correctly and wake up late or realize you've missed an important appointment.

Last night I dreamt I overslept and was late for my own birthday party and my siblings had to come to fetch me. They came in 2 cars, one a late model Ford truck driven by a stranger. Now who the heck was he and what was he doing there?
