You look down to see your fingernails and toenails slowly turning black, as what a light dusting of what you now suspect to be fur starts growing all over your body. Your nose starts to change shape and color, and for some reason, it makes you think of...
"This can't...I'm not a dog!" You shout out flabbergasted.
And just as suddenly as they started, the changes stop. You are still humanoid, but you have fur, and dog ears, and a tail. Your face is still fairly normal apart from the fur, but your nose is dark and rounded and a little leathery. And your teeth, well, as you noticed earlier, they are a bit sharper. Your nails are not yet claws, but they're definitely thicker and darker. However nothing else is happening. It's like the moment you complained, the changes halted.
You still not thinking straight, although no longer from drowsiness but now from shock. What was happening, were you losing your mind, or were you turning into an animal? How could this happen? And what do you do now? You can't go out like this, you'll be a total freak. You study yourself in the mirror, hoping maybe you could hide your changes, but they just seem to obvious.
"Yeah, everyone else is going to think THIS is normal," you snort sarcastically.
You hold your tail out of the way and use the toilet -- life goes on -- then pick up your pajama bottoms off the floor and head for your bedroom to try to wrap your head around this. That's when you see it. The pictures around your bedroom, some with you and family, some with friends. In all of them, you have fur. And triangular ears. And...is that a tail??!
Maybe...the way you are now is normal. But why? It couldn't be just because you said it, could it? You were just being sarcastic...but what if it was taken literally? Suddenly, the dream you couldn't really remember flashes into your head. What if it wasn't a dream? What do you do next? Literally every word you speak could be taken...literally.
