Your gaze goes between the bowls and the plaque several times trying to figure out which of these bowls you should eat from. It's clearly some sort of riddle meant to give you a hint on how to proceed, but try as you might you can't determine the answer. To make matter worse, whatever's controlling this dream (or whatever it is), has seen fit to plague you with some old tune that you're sure you've heard but can't quite place. Thus making it harder to concentrate. After what must be another few minutes before you grab the second bowl of oats, almost at random. You stick your hand in the bowl and shove a mouthful of the dry oats into your mouth and, with some effort, force yourself to chew and swallow them. As soon as you do the bowl drops from your hands as the walls and door before you fades away leaving nothing but blue sky and green green grass.
Checking your fingers you can see why the bowl dropped, outside of the shock of seeing everything disappear. Your fingers have shrunken and fused. Your hands have narrowed to the point where they more resemble the hooves of a deer. A feeling of dread comes over you as you see fur growing from between you former fingers and down your wrists. As the fur spreads down your arms, they straighten out before you, loosing muscle mass and changing shape, becoming front legs. Your neck thickens and lengthens in contrast to your narrowing head. As the fur surrounds your skull and crawls down your back and around your torso you feel your body changing. Standing on your hind legs suddenly becomes impossible and you fall forward as your spine shifts to give you a quadrupedal stance. You crane your neck and watch helplessly as your back legs shift and your toes shrink. The final touch is a brown and white deer tail that pushes from the base of your spine.
You stand on all four legs, hoping to wake up soon, before coming to the sinking dreadful feeling that you're not dreaming. You're a deer, and judging by your lack of antlers, a female. A doe. Suddenly it hits you. The song that was playing. Mares eat oats, and does eat oats..... You can't remember the rest of it. In fact you can't remember the first part. You can only remember the part about does eating oats. You see a few stray oats from the bowl you dropped and decide you'd better finish them. When you look up from your meal you realize that your surroundings have changed. You now find yourself in a forest, which after all is where a doe like you belongs.
If you could laugh, you would at the silly dream you had that you were a human.
