Can you imagine eating your bed, or falling asleep in a plate of food?
I don’t recommend it. Since most sheep eat grass and also sleep on it, do you think it is like that for them? I’ve noticed that they instinctively paw the ground to make a scrape before they settle down. They are often snoozing with full tummies when I check them all in the middle of the day. If it is hot sun or raining, they tuck up under trees or bushes for shelter, otherwise they scatter across the slope. Usually the mums demand their lambs curl up with them, but often the older lambs rebel and go off exploring in a gang until they are hungry or sleepy.
One of my favourite duets for upper voices is “When at night I go to sleep” by the wonderfully named Engelbert Humperdinck for an 1893 production of Hansel and Gretel.
