Blackout. [COMPLETED]

Progress.

"David, David, David," I yelled, tripping over my own shoe laces as I ran down the hallway. Don't forget, I thought to myself, Don't you dare blackout now.
 "Yeah? Hello?" I heard him calling from behind me. I spun around and saw him leaning out of a doorway that I'd just passed. He ran over to me as I buckled over, trying to catch my breath. He held my shoulders and pulled me upright, staring at me. He leaned closer expectantly.
"Ayla," I stammered, taking gulps of the cool air. "Ayla is, Ayla, I'm..." I was finding it unusually difficult to breathe. This wasn't exhaustion, I'd only ran about 10 metres at most. My heart was pounding in my chest.
"Ayla is Ayla? Come on, let's go outside, I think you're having a panic attack," he muttered. "Hey, you," he said, pointing at the woman who has just shown him round. She nodded. "Where's the garden?" Sighing, she pointed towards a door at the end of the hallway, that had peeling paint and was missing a doorhandle. Clearly, they hadn't renovated that bit.
David took me outside and sat me down on the cool grass. I instantly lay down and was shortly joined by him lying beside me. I stared up into the grey sky, trying to control my breathing.
"I can't believe it," I said flatly when the panic attack had passed. I rolled over onto my side and ran my hand over the cold grass.
"What?" David asked, turning to face me, and watching my hand stroke the ground. 
"My name," I mumbled. "I'm called Ayla."
We lay in silence for a few minutes. There was nothing to be said. Well, maybe he was thinking of what to say, but I was just waiting to suddenly appear in the middle of a car park and have no memory of this.
"You won't black out," he mumbled, smiling at me. "It's a lovely name. Reminds me of something," he said, sitting up on the grass and twirling a flower between his fingers.
"Something nice, I hope," I replied. I felt a huge sense of relief. I heard the click of a pen lid and looked up as David took my arm and put it across his lap, and began writing on me.
"What are you doing?" I craned my neck round and tried to see. He'd written 'Your name is Ayla and you'll be alright' on my arm, just beneath my tattoo. I traced over the writing with my finger, admiring how neatly he could write using biro and arm.
"It's not permenant, but it'll do," he said, lying back down letting out a sigh. I looked around the garden; the towering fences and lonely trees seemed familiar.
"Ayla," David laughed, shoving me.
"What? Sorry."
"You weren't listening to me, I said your name like a million times."
"Oh, um, I forgot I had one."
David laughed. "Yeah, I forget my name all the time."
I smiled down at him and he smiled back.
"I don't, I'm Christina the fourth," a sudden voice from behind me said. I turned around and saw a young girl crawling towards me.
"The fourth?" I asked, watching as she sat down beside David. She nodded.
"One, two, three, four," she said. I nodded and smiled.
"I'm Ayla," I replied. It still felt weird and unnatural.
"David."
"Nice to meet you Ayla and David," she said, holding her hand out to me. I shook it in response.
"So how long have you two been dating?" she asked enthusiastically, grinning at me.
"Oh, er, no we aren't like, we're more kind of, I don't know how you'd describe it because-"
"I'm helping her out," David said, sitting up and putting his arm around me.
"Aw, you aren't going out?" She sounded genuinely disappointed. I shook my head. "That's a shame."
And then she just walked away.
"Great conversation," I muttered as David slipped his arm off of my shoulders.
"Yeah, well, we are in a loony bin."
"You can't say that!" I replied, looking behind me to see if anyone heard. His cheeks turned red and he looked around to check, too.
"What the hell is that?" he said, standing up and walking towards a pond that was hidden behind a weeping willows branches.
"Water," I replied. He looked round at me and rolled his eyes.
"That," he responded, pointing down into the pool. There was a light blue glow coming from deep down in the pond that was sending sparkling waves of light to the surface and rippling across the water.
I kneeled down, rolling up my sleeves, before plunging my arm into the pond. The icy cold water felt like shards of glass against my skin and numbed my fingertips instantly. 
"Shi-  that's cold," I stuttered, pulling my arm out and drying it with the hem of my shirt.
"Should we ask somebody?" he said, leaning down to try and get a closer look. "Maybe someone dropped their phone."
"I don't think a phone would glow that bright after being dropped deep into a huge amount of freezing water."
Suddenly, the light flickered into a bright white beam that shone straight out of the water and illuminated the tree above us. For a moment, we were encased in a glowing shell. As suddenly as it appeared, it disappeared, and the water in front of us was a dark and murky black colour.
"Maybe they just got a text," I muttered, staring into the pool in awe. David let out a nervous laugh and I took a deep breath.
"Did that just happen?" he asked, watching as a gold fish swam in a figure of 8 near the surface of the pool before disappearing.
"I guess so." I rubbed my eyes, seeing an obscured line in my vision. "I think I've been blinded."
"Yeah, same," he said with his eyes closed, holding his hands out in front of him. "Turn the lights back on, Ayla. This isn't a joke, I'm scared of the dark!"
"Very funny." I dipped my finger into the icy water and then dragged it across the back of his neck. He span round and slapped my hand.
"Ow!" I said, whipping my hand away.
"That's cold!" he replied, rubbing the back of his neck.
"You're not blind anymore, though."
"Yeah, you should be a doctor," he said sarcastically. I smiled. I seemed to feel a little more comfortable around him. Since I'd met him, I'd felt that there was such a huge possibility that he was lying to me, that he was the bad guy, that I hadn't let myself fully relax. For the first time, I realised that he felt like a friend to me. He smiled at me before standing up and making an opening in the hanging leaves of the willow. I walked through into the garden and noticed that it was sunset, and that there was pink and orange light glowing through the fence.
"Let me take you home," he said, linking arms with me and leading me back through the hallway. People had been allowed to leave their rooms, and all the doors were completely open. Some people, including the young girl, were walking around the halls and attempting to socialise, whilst others sat against the back wall of their rooms and stared at us as we walked past.
The girl who had just been interviewed was now strapped to a bed, but her door had tauntingly been left open. She seemed to hiss at me when we passed her.
Just before we left, I noticed one closed door. I looked at the writing on the sign.
'UNKNOWN PATIENT, 241105'.
"Maybe that was me," I said. There was a padlock on the door that looked old and rusty, as if it hadn't been opened for years. 
"Woah," I said, holding the padlock in my hands. "How long ago was I here?"
Suddenly the lock snapped in my hands. I moved my hands away as it dropped to the floor. Despite the noise not being particularly loud, everybody heard it, and stared at me. I moved back as the handle rattled and, after a while, it opened.
"Finally," a raspy voice muttered as the door was slowly pulled open. The figure was dressed entirely in white, but had unusual dark brown stains from their chest downwards. There were similar stains splattered across the walls of their room.
"How the hell did you get out?" a worried guard behind me said, his voice breaking.  
"Thank you," the figure said to me, his black eyes terrifying me. He held up my hand and kissed the back of it. His breath smelt like blood and his hair was long and matted. 
"I guess I owe you," he whispered as he lowered his face towards mine. I could hear each raspy breath that he took and I could see dark stains on each of his teeth. When I leaned away, he leaned closer.
"No, you don't, it was an accident anyway," I said nervously as David tugged at my arm.
"No, really," he replied, grinning. "How ever can I thank you?"
"Just leave her, man," David said nervously. "Just say thanks and leave it." 
"Oh, I couldn't do that," he said. His voice sounded overexaggerated as he put his hand to his mouth in shock. "How could you suggest such a thing?"
I could feel the presense of guards surrounding me, mumbling nervously to one another.
"I guess we're in the same situation." The figure pointed at the name plate on his door. I nodded as my stomach twisted into knots. David was pulling me towards the door, but I was locked in place. There was something horrifically familiar about the smell, the eyes, the awful blood stains on the walls.
"We were both here for the same reason though, right?" A grin never left his lips, and his gaze never left mine. I shook my head.
"I don't know why I was here," I mumbled. I was so nervous it was almost a whisper.
To my horror, the figure in front of me pushed his finger into a healed wound in his stomach and began to pull at it until the end of the scar ripped open, covering his hand in blood. I slapped my palm over my mouth to try and stop myself from screaming out in shock. He smeared his hand across the door and curved it around, concentrating on the pattern. 
'Sacrifice'. It said 'sacrifice'. As I stared at the blood on the door, the figure pushed material against his wound to stop the bleeding.
"W-what did I sacrifice?" I stuttered. I was terrified. David was too, as his arm had gone limp against mine.
"Something very important."
"What?" I whispered, feeling David tense up next to me. 
In silence, the figure moved his lips slowly. I stood apprehensively as I watched them. The entire time, I saw the blood on the door in the corner of my eye. The blood on the walls. The black suits of the guards either side of me. Davids hand holding my wrist. The ripped straps on the bed. The crack in the window. The withered plant on a small table in the corner of the room. I saw it all before I saw what he said. And when I saw what he said, I saw nothing. Everything went black.

"Murderer."
