So i keep having dreams about getting home late from school or missing the school bus...?

I've had this dream maybe 20 times almost back to back. it starts off at the end of the school day. i insinuate that i miss the bus because i'm just in the parking lot trying to catch a ride from someone i know that drives. every time i have this dream i catch a ride from a different school mate. i always get home on time but its the overwhelming feeling i get between point A and B. i feel anxious, rushed, nervous, left behind, like i let my parents down, etc. its really overwhelming. well i always find a ride but most of the time its with people i'm really uncomfortable with (always a guy who i know likes me.) the ride home seems so drawn out and tense. my dream ends at the end of my driveway. so what does this mean? why do i keep having this dream. i've never missed the bus so i dont know what triggers these dreams. anybody have a clue???
