Strange reoccuring dream...?

Ok so a little background info, im 18 and in the Australian Regular Army.. Anyway, I keep having these dreams where I'm with a mate and we are patrolling with full packs and for some reason i keep stepping into potholes and keep jerking awake to steady myself... It doesnt bother me as I USUALLY dont notice the twitching but it drives the missus up the WALL! So i'm just curious as to what everyone's take on it is...
