Lab Rat

My eyes snap open, squinting in the sudden light. The blazing white light burns directly into my eyes, sending blurry streaks of yellow spiralling across my vision. I hear the low hum of chatter, snatches of conversation.
"running some tests-"
"some negative results..."
"are you sure?"
"all in good time-"
"she's awake! See! She's awake!"
By now my eyes have adjusted to the bland white of the lights. I see men and women, all crowded round me, dressed in plain white lab coats. They're all scribbling down notes, clipboards in hand, staring at me like I'm an animal at the zoo. I squirm under their gaze, straining against the metal rings that encircle my wrists, chaining me to the operation table.
"One more test..." a cold, emotionless female voice murmurs.
The white lights intensify as a man wearing a surgical mask makes his way towards me, clutching a long needle in his papery white hand.
"No!" I screech, struggling against the heavy metal chains.
This is met with silence, weighing heavily on my shoulders. The man carries on, ignoring my cries of protest as he inserts the needle into my arm. A stab of pain shoots through my body. I jerk suddenly as the liquid enters my system.
"What is this...?" my words merge together, my mouth numb. My question is met with silence, even heavier than before. I watch as the man turns, picking long knives and surgical instruments from a trolley, my heart thumping. I try to cry out, but all that leaves my lips is a low moan. Darkness clouds my vision and it starts to blur at the edges.
"No," I murmur. "No..."
I fight to keep my eyes open; I must stay awake. I don't trust the man, or any of them; with their too-white lab coats, their stony expressions, their stiff, rigid posture. I won't succumb to whatever it is that they've injected in me. I feel my eyelids growing heavy, sleep luring me in, engulfing me like a warm blanket. The last thing I see is the man standing over me, a surgical knife in hand. His blue mask covers most of his face, but I know that he is smiling.
