(Based on a nightmare of mine, which is sort of like Asian horror meet H.P. Lovecraft, although written with far less skill than the actual master himself. I was not in the nightmare, but rather a young Asian woman instead. It's my feeble dedication to my favorite movie genre and favorite horror writer.) 

Sleep paralysis, a terrifying journey into the darkest recesses of the human mind. I feel as if these horrid events are getting increasingly worse by the passing of time, all the more so due to my absolute dread at the very thought of falling asleep. I, Ayano Matsuki, told no one of this condition, and merely hoped that these unnerving problems would eventually cease. Night after night it was the same however, and each morning I awakened feeling weaker and more dead than alive. Doctors could do nothing and no one would believe anything I said about the situation anyway. The drugs they prescribed were useless, since by supposedly helping me to sleep better, it only worsened my already pathetic state of mind. My parents tried their best to help by giving me an old picture of Ryoko, my late grandmother, to hang in the room in which I slept. This seemed to help matters at first, and for several days afterward I was able to more or less sleep peacefully. The strange thing was that I never looked directly at her picture, for reasons which could not be explained or understood. The presence of this seemingly wholesome and loving woman should have set my mind at ease, but in fact just the opposite was occurring. I could not bear to glance upon that smiling expression which looked down on me always, for fear of going mad over something I suspected had already happened. The fact that she bore a more than passing resemblance to some ancient and malignant ancestor who haunted my nightmares, was more than my already fragile nerves could handle or cope with. It seemed to know when everyone else was away from the house, and knew that nothing could prevent her from striking now that the right moment had arrived. Finally, overcome with fear and forced against my will to look upon that terrible picture, I knew at last what true horror and madness was! The sudden screams which emerged from my throat was cut off by the appearance of that unimaginable terror, and knew that death had arrived in the form of something much too terrifying for words to ever describe!

Emerging from the shadows, a hideous entity slowly creeps closer, standing over me as she smiles before pressing her entire weight upon me. The pressure on my chest is nearly too much to bear. I feel as though every last breath is being squeezed from my body while being paralyzed with fear. Unable to move and powerless to resist, I am overcome with horror as she smiles and whispers softly, letting me be assured of her complete possession of my entire body. Trying to scream, all that emerges is a short gasp of air as I slowly suffocate as the nightmare becomes reality. My parents found me that morning, with a frightened look of horror on my face, as if trying to utter a scream which never came. Everything would be explained away as an unfortunate overreaction to those drugs, which lately had been consumed in far too many quantities, and family and friends would surely mourn my death. And when my little sister Miyako eventually moved into that room, everyone but her failed to notice that picture had suddenly taken a change of appearance, and looked more and more like myself with each passing day!
