Psychoanalytic theory can be used to analyze the narrative mode of the film to explain psychological problems from the perspective of dreams. Based on the theory of embodied imagination, this study uses the text analysis method to analyze the film constructive narrative mode embodied in the film Deep Sea through the case study. The film constructs the sand play narrative space and uses nonlinear narrative techniques to reflect the three major characteristics of the film’s constructive narrative mode based on the theory of embodied imagination: the integration of authenticity and illusion in image construction, the penetration of emotional emergence and the process of image experience, and the realization of healing effects both on and off-screen. In the research process, the advantages and disadvantages of film works are analyzed. The advantages of free narrative logic and immersive movie-watching experience are accompanied by the disadvantages of increasing the threshold of movie-watching and large investment risks. This study provides a reference for the construction of the theoretical system of film constructive narrative mode.
