I'm off to bed

A dark-colored dog emerges from a pet carrier, walks forward, and then the scene cuts to a large gray suitcase lying on its side in the same room, with a crumpled white cloth on the floor nearby. The dog reappears from the carrier, walks out, and the scene cuts back to the suitcase and cloth. This sequence repeats. The setting is a room with a white brick wall, a filing cabinet, and a staircase.
