Yet another baffling dream

Last night, I dreamt that I was in a hurry to get to school... so there I was driving to the carpark and terribly worried that I would not be able to find a parking spot. Luckily I found a couple and did my parking, however, the gear stick in 'park' would not keep the car stationary like it was supposed to. I was very anxious and just kept changing gears between 'park' and 'drive'. And then, the gear stick broke off and the car started sliding backwards on the slope...
