The twinkle bursts into flashes of memory that assemble your senses into a perception of where you are. Tendrils of deja-vu tug at your mind reel your conscienceness to the disturbing truth. This looks like the padded cell from a movie or television show.
Another tug, this time on your arm, turns into a sharp pain of an needle snaking back to an IV bag.
Footsteps grow louder, then faster. The room starts to fade. Voices. Darkness.
...
You awake with a sense of groggy dread and force your eyelids to open up (very much against their wishes). At first the bright light blinds you and hurts your poor retinas, but after a few seconds you adjust and take a look around. You appear to be strapped to a gurney in a narrow (but brightly lit) corridor. The walls and ceiling are white and spotlessly clean. The floor... well, you can't see the floor. In the distance you can hear a faint humming sound, but you appear to be all alone at the moment. Well, now what? Perhaps you could call out?
You could also quietly struggle against your restraints.
