At the beginning of the twentieth century, along with Freud and Jung's theories about human as well as World War, a new approach was formed about human and his mind, effect of which in literature can be considered as emergence of mind fluid flow. In this style - as a rebel in story writing - the author, unlike classical stories, tries to penetrate deep into their minds instead of addressing the appearance of characters, and narrate the story through the minds of characters. Ghassan Kanfani is one of the first pioneers of this genre in Arabic literature. Ghassan wrote the story Ela An Naoud "إلی أن نعود" in 1957, which penetrates deep into the unconscious during the course of self-awareness. The whole story is in progress in the minds of character and on the surface before word, and character mind is flowing between pleasant and unpleasant memories of past. This paper tries to investigate the fluid flow of mind in a descriptive-analytical way and show that Ghassan has selected the components of this genre, including internal dialogue, mental time, free thinking, cinematic techniques, and poetic language, etc., to reflect social realities.
