Each and every face has turned to stare at you with a look of surprise, confusion, and...fear? The migraine flees as quickly as it came and you can finally see why they are so appalled. You look at yourself and see… a dragon. But looking at the peoples around you, you don't seems to be any taller than before.
Inspecting your body more closely, you note that while it's now mostly covered in night-blue, almost black scales, your underside and the palm of your "hands" were sky-blue. Speaking of your hands, while they were still perfectly functional as such, they seemed to be just as adept at supporting part of your mass, like you were now made to walk on all fours.
This prompted you to look at your legs, moving them a bit to see how they worked now. To your amazement, they seemed to let you walk both on two and four. You were also surprised by your foots, who made you think of an ape's ones. While not as dexterous than your hands, you were still able to grab objects with them, having opposable thumbs there, too. Flexing one foot, you discovered that, if walking on two, like the human you used to be, you would use your soles, on all four you would be digitigrade, a bit like a big cat.
You also discovered that, wile at first neither your foots or hands seemed to have any claws, it was because like the one of a cat, they were retractile.
Those two similarities with a cat made you wonder if you weren't some sort of draconic feline of some sort, but a look at your snoot dispelled that notion.
You then decide to inspect the things you didn't have at all before your transformations, namely your tail and wings.
Your wings were nothing special, just some big scaly bat-like wings, like expected on a dragon. The only thing of note being that, while they were entirely of the same dark-blue than your back on the top-side, the skin on their underside was as the same color as your palms.
The tails was another thing. Your first surprise being that it ended in some sort of blade, almost like nature, or whatever magic changed you into a dragon, saw fit to give you a dagger you couldn't loose. Then, around 10 centimeters after the end of the blade, what looked like fur of a blue so pale it looked white was goring out of its' top, forming a mane of some sort. On closer inspection, the mane seemed to be made of hair-like feathers, rather than true hairs. Following said mane, you found that it trailed back to the top of your head, where it was gently nested between your horns.
Now that your self-inspection was finished, you turned back to the peoples around you noticing that, while wary of you, they had been transfixed by the spectacle you offered them. You suppose that when a dragon come to town, they're usually more of the rampaging variety than the self-inspecting one.
You try to say hello, wanting to reassure the villagers that you weren't a danger to them. Instead, all you manage is a growl. A very cold growl that freeze the near-by stall, making everyone flee in panic.
