The boundaries between dream, memory, cinema, and different parts of the self dissolve to ravishing effect in this latest short by Los Angeles-based Chinese artist Zhuoyun Chen. Moving woozily between diary, autofiction and free association, “It Must Be Because I Decided to Leave” is awash with half-remembered exchanges, infectiously surreal images and the narrator’s desire to make sense of things, which never quite happens. Oneiric motifs of all kinds abound: Rocks are clasped by hands or merge with faces, screens appear in windowpanes or headlights, a gleaming red sports car spins in the California desert, a shadowy figure walks into a cave, and a dog rises up from a pool in reverse, its scrabbling limbs rendered in elegant superimpositions. The narrator shuttles through thoughts of desire, family and dislocation and refers to any number of “yous” and “Is”, although they could easily be one and the same. If “we all have landscapes inside”, this is a journey through them.
