(Sherlock's POV)
"I swear it was there!" I exclaimed. "It was looking at me with these red, beady eyes!"
For the twentieth time this month, I had woke my flatmate in the middle of the night. Every time he came to look at the monster, it disappeared.
"Nothing was there! You're high again, aren't you?" He retorted.
I sighed. "No, the only medication in my system are the sleeping pills I took to sleep through that. Clearly, I should have taken more of them."
"You utter wanker! Drugs are the reason you're in this mess! You're not overdosing on sleeping pills, or I swear to God I'm moving out." He exhaled deeply. "Now go to sleep!" He slammed my bedroom door.
I closed my eyes, steadied my breathing, and played violin. A few moments later, my flatmate came in and chucked a pillow at my head. Then, he took a pair of handcuffs out of his back pocket.
"What are those for?"
"So you'll stop making so much bloody noise!" He moved to cuff me, I fought him off the best I could, running all around the flat, kneeing him— well, you know where— I tried everything. But of course, he has always been the stronger man. I felt my muscles tense as he overpowered me and cuffed me to bedpost. I bit his hands and he exclaimed in pain.
I was shaking, my eyebrows furrowed, tears flowing down my face. "NO, YOU CAN'T DO THIS! IT'LL KILL ME FOR SURE! Please!" I cried hysterically. He answered by tying a strip of fabric over my mouth.
"Some of us have real jobs, Sherlock. I have to wake up early, cheers." He said before leaving.
I laid awake, staring at the ceiling for hours. I fell asleep, then I woke to the monster tearing long cuts down my torso. I could taste the cologne on the fabric as I screamed into it. I shook my body in attempts to wake someone, anyone. This movement moved the bed loudly. My wrists throbbed from all the chafing my struggle caused.
Again, my flatmate entered the room, slamming the door in our landlady's face who had also arrived in the hallway.
"Shut up! What the hell is wrong with you?" He asked before begrudgingly removing the handcuffs and the mouth covering. "Clearly these are no help."
I took many shallow breaths in. I gripped his wrist with my shaking hands. He glared at me. "You... have... to believe me."
"Why?" He crossed his arms.
"Because," I took one of my hands and began unbuttoning my shirt. He averted his eyes and tried to move, I kept my other hand around his wrist. He stopped resisting, staying in one place, but his gaze stayed averted. I tapped him, he slowly looked. His eyes grew wide, seeing the deep scratches.
"Where did these come from?"
I took a deep breath. I knew he wouldn't believe me. "That thing."
He furrowed his brows, I pointed under the bed, and he rolled his eyes.
Then I turned to the window and began my deductions. "There's no sign of forced entry from the windows. The remain locked, and maintain their layer of dust. If someone who had broke in the door, you would have heard it."
He nodded slowly. "Do you have a solution?"
"Contacting paranormal investigators. One will be here tomorrow."
"And for the rest of tonight?"
"I have a theory, a suggestion." I replied.
He crossed his arms, "Well? Out with it."
"You won't like it."
"Try me."
"It follows me, even if I move to the couch to sleep."
"Okay."
"But it's afraid of you."
"... Okay."
"It flees whenever you're around. So, perhaps if you stay here with me—"
"You want me to sleep with you?" He laughed awkwardly, looking to the ceiling.
"That is what I'm suggesting."
He thought for a few minutes, with his leg bobbing, and his jaw ticking. "Fine."
We got into bed together. I laid on my back and faced the ceiling. My friend faced away from me, toward the wall. I could smell his cologne, and hear him adjusting his position. I closed my eyes, focusing on his scent, and fell asleep.
I woke up to the familiar presence of the creature. I saw that my friend had left. I struggled, and screamed, fighting against this creature, No one came. Why had he left? I warned him that it would return!
The creature's breath was akin to rotting flesh. Its grip was like the roaring tide, too powerful to escape. Still, I thrashed about, screaming like a madman. It started crushing me, and enveloping me in its essence.
I tried to hold my breath, it didn't last long. Its red piercing eyes met mine, I shut them tightly. The scent overwhelmed me, just as I felt consciousness fading, I was jolted awake as it tightened its grip, and began breaking my bones. I had no more breath left to scream, thus, it devolved into quiet whimpering.
My life flashed before my eyes. Everything that had happened, everything that stayed locked inside my mind as possibilities. I lost all hope, and slipped into darkness.
