Done Unto Us by Gerhard Jason Geick and Victoria Marsh
It begins in her head, and then the things in her head become all too real.
While she was in the hospital, she had vicious night terrors. They took her back in time, and she still suffers. In her sleep, she is pursued by a faceless boy. He chases her through the sterile hallways of her elementary school. Inevitably, he catches her, and he puts his body over hers. He holds her hands tight to her sides so that she cannot move – and even at that young age, she takes notice of his penis pressed against her thigh.
He presses his mouth to her ear, and he says, "I will kill you and resurrect you. I will steal the very breath from your mouth, and I will bring you back to life, and I will do this to you over and over and over again until there is nothing left of your soul but a broken husk." - and then he does as he proposed.
The events in this story are true to the extent that this is how they are remembered.
