Abstract: Despite being popular with the readers and literary researchers, Pavel Sanaev's novel 'Bury Me Behind the Floor Molding' is still understudied as a literary work with a specifically organised imaginative world. In her research Belikova demonstrates how the concepts of space and time typical for a child are replaced by the 'adult's' worldview as a result of his parents' pressure, and describes the expressive means used by Sanaev to depict a child's worldview. The research methodology used by the author of the article is based on discovering chronotopic coordinates of 'unhappy childhood' (based on the concepts of R. Litvak and M. Duranov). The literary analysis of the novel allows to define specific features of the imaginative time and space where Sanaev's hero lives. Through creating a unique imaginative world in his novel, Sanaev demonstrates how the main hero's mind and perception change when he no longer believes in the existence of 'happy space' or feels the time in a cyclic manner (which is typical for a child). The main hero of the novel perceives the time in a linear manner and tries to 'catch up' with the time and dreams of the time to stop. Psychological and existential problems that dominate in the novel are reflected in the expressive means used by Sanaev and chronotopic coordinates that bring a stronger artistic force to Sanaev's ideas.
