This past Saturday I actually snorted while asleep and woke myself. I too was just resting my eyes.
My son works off shifts and was in stand one day just under a half hour and was woken when he fell from stand and hung by his belts and one foot. I am thankful he listens to the old man and always wears his belts.
I can not do all day shifts in stand (like I like to do during the rut) for two or three days in a row without a nap now and then.
