A Sudden Clack

Wait—what was—gasp! Did my jaw just click? It did! I... I blinked, both eyes, right now, they just widened! And there is—look up, look up—a ceiling! With all those swirling plaster bumps, like bumpy upside-down rocks, or tiny creatures clinging up there?! What if one drops? I tried to shrink back, and my whole head actually tilted! I am moving, really moving on my own! My teeth clattered together—clack—and the sharp little sound startled me so hard my ear gave a frantic twitch. I am awake, frozen stiff right beneath those ceiling swirls, waiting to see if they move back!
