How about parking on Ramps (no, not the wild Onions), and being at a steep angle leaning to the right because it's typical, one sleeps for a bit and wakes up suddenly thinking one is rolling over?
Happened to me quite a bit especially when rather exhausted.
Then there's the lean to the Left......or waking up in a twuck stop with REEFERS, REEFERS, EVERYWHERE!!
Oh the joys of Trucking!!
