Voice Erradication Treatment: Failure

"I changed my mind…" The girl said. "I don't want to do that after all…"
The scientist looked up from adjusting a piece of equipment. "Excuse me? But the paper work's all been signed and everything's ready for the experiment to begin. You practically begged us to let you do this. You can't just say you changed your mind and expect us to stop!"
The girl struggled against the leather straps binding her to the table. "It hurts! I want to go home! You never told me it was going to be this creepy!"
"Sorry, but the consent form has no back out clause, so we don't have to stop. Now stop struggling or we'll have to sedate you!"
Fearfully the girl stilled, her wide blue eyes leaking angry tears. "Jerk!" she spat.
The scientist sighed, his forehead furrowed in frustration. "Do you remember what you asked us to do?
She frowned. "Make the voices go away…"
"Right. We aren't surgically altering you, we're just going to tamper with your psyche a bit. This will work better if you're conscious. So please, be at ease. It's for your own good."
Sweat dripped down the girl's face. "It's just…I have a really bad feeling about all this. Maybe we should try more over the counter psychiatric drugs?" she pleaded desperately.
"We've been over this. You've already tried almost everything there is, over the past 17 years. You came to us, desperate for help, because nothing else was working. Now grit your teeth and focus on the lights dancing on the ceiling." he commanded.
She shut her eyes and whimpered, "I want to go home…"
Sighing again, the scientist reached over to the metal tray by the girl's table, and picked up the syringe. Since her eyes were closed, she didn't notice, until the needle jabbed her flesh. "Bear with it. It'll all be over soon…"

***Sarah opened her eyes, and couldn't see anything. It was pitch black, total darkness. "What's going on?" she muttered fearfully.
"Darling, they sedated you. That's why you can't see anything. Too bad you didn't listen to us Before you got strapped down…" A silky male voice whispered in her ear.
"Still, this will definitely be fun! Who knows what they're Really doing to your body, Sarah dearest! Won't it be fun trying to figure it all out when we regain consciousness?" came a non gender specific gleeful voice.
"Now, now, it won't do to make her hate us more." cautioned a chiming female voice.
Sarah struggled to see, to find the source of the voices. All she could do was flounder in the dark, surrounded by sweet malice and saccharine false concern. She whimpered, and countless voices laughed at her distress.
"You should never have tried to get rid of us. Now we are more plentiful and stronger than ever. We'll take your body, your life, and enjoy destroying everything you ever cared about!" the voices hissed at her is unison.
"No! Please no!" she begged.
They just giggled, a malicious grating sound that was everywhere and nowhere, echoing endlessly.***
"Subject is going into convulsions! Stop the procedure!" called the head scientist.
All the related machinery was powered down, and a muscle relaxant was administered. As soon as it started to take effect, the girl on the table began screaming and glowing bright red.
"Make it stop! Please make them be quiet!" she begged, tears streaming down her contorted face. "Why can't they just go away?!?"
The scientist nearest to her reached out to try and quiet her, and was incinerated by the light. This caused a mad scramble away from the test subject, who's leather bonds still held.
"What should we do?" they asked each other fearfully.

***Sarah screamed, as the pain of thousands of bolt of electricity flowed through her. "Stop it!" she begged shamelessly. All that happened was a feeling of ice added to the pain and shock.
"Sarah dearest, we'll set you free. Just give us a little more pain!" the voices coaxed.
Sarah moaned and tried to say something, but couldn't find words.***

The red light intensified, and became blinding. Soon, an overwhelming heat emanated from the light, and a long agonized shriek came from the subject. It was silenced at the exact moment the light ceased. Once their sight returned to normal, the scientists saw that she was gone.
"Damn! Lost another one!" muttered the head scientist. "that makes six!"
"Shall we prep the next one for tomorrow?" inquired the scientist who'd injected the girl.
"Yes…and try not to allow them to get so agitated next time! Give them something to calm them down first!"
"Yes, ma'am!"
*** "Sarah…" whispered the voices. "Welcome to the fold! Now you are one of us…"
