Ömür İklim Demir’s novel Kum Tefrikaları is a postmodernist text with a metafictional quality, consisting of two narrative layers: fictional and historical. Focusing on the experience of space by different subjects in different time planes, the novel includes categories of space and area such as city, countryside, interior and exterior spaces, home/nest with its functions of residence, living room, attic and various rooms, ruined spaces, and nooks and crannies with their functions of dreaminess and residence. The experiential, internal, and dreamlike nature of space is created through the practical, mental, and emotional practices of fictional characters. According to Gaston Bachelard, the poetic space categories encompass the imagined or visualized spatial designs present within poetic narration. In the novel, poetic imagination is realized through thematic focuses such as dream-interiority, life, and death. The objective of this study is to elucidate the process by which fictional space is produced, drawing upon the theoretical framework of poetic space developed by Bachelard. The study will assess the fictional production of space and the production of space in fiction from multiple perspectives. Therefore, drawing from Kum Tefrikaları’s experimental first novel, the objective is to ascertain the efficacy of contemporary literary theories in 21st-century Turkish literature within the global literary canon.
