wrong side of the bed

Jolted awake by a mobile phone alarm that'd been thrown to the opposite end of the room the night before as I've the tendency to switch my alarms off in my sleep. It occurred to me early on that if I was ever to get to work/school on time the clock needed to be a good many feet away to make any such attempt by my sleeping otherself foolhardy. Now with my decaying wooden single bed placed up against the room's whitewashed brick wall I threw myself out of bed and like a stunned blackbird who'd flown into a glass window I fell back almost unconscious. Rubbing my head I laughed to myself as I had quite literally got out of the wrong side of the bed.
