MT-V 4.1- Christopher Doll, “Was it Diegetic, or Just a Dream? Music's Paradoxical Place in the Film Inception"
Between "diegetic" film music (heard by the characters) and "nondiegetic" film music (heard only by the audience) is a paradoxical space called the "fantastical gap." A film such as Inception (2010) makes traversal of this gap into an overt theme, obscuring our sense of place to such a degree that even the literal plot of the movie is open to interpretation, and thus also illustrating the extent to which filmmakers can manipulate an audience's understanding of the filmic world through the blurring of the diegetic/nondiegetic divide.
