"The Little Demon Girl" by Josh Duer

The story is told in first person from the protagonist Joshua. He confesses in the first chapter that he believes he is slowly going insane and the only thing that keeps him stable is the three-foot tall demon girl who lives in his closet. She tells him stories and sings him songs to ease his mind. When he hears her voice or is hypnotized by her gaze, he fades from existence and enters into a dream- like state of his consciousness. Each trip from reality brings him closer to understanding the purpose for his seeming departure from physical to psychosomatic realms. During the course of his assorted journeys, he meets an array of interesting creatures and people, each with their own stories or dilemmas. He encounters difficult puzzles and must overcome arduous or sometimes frightening tasks. Despite what the demon girl tells him, the ethereal shifting between realms, eventually takes its toll on Joshua when he frequents trips to the graveyard of past memories and converses with his shadow, a representation of his former self, who convinces him not to trust her. The story gradually winds down as he pieces together his past and overcomes various life obstacles, which dwelled in his conscious and eventually drove him to current mental state, and he finally realizes his past and accepts his existence.
