two people in a room with light-colored, plank-style flooring and walls, creating a box-like effect. A rectangular opening in the floor reflects a man lying on a yellow and black surface, likely a bed or similar furniture. He is wearing a black jacket and has a phone in his hand, as if taking a selfie. His mouth is open in an exaggerated expression. The reflection shows another person partially visible on the left. To the right of the rectangular opening, a person is sitting on the floor, wearing a dark-colored jacket. The top of their head and their hair, held in place with a clip, are visible. The setting is likely an exhibition or art installation designed to create an optical illusion. The specific location in Sofia, Bulgaria is not clear from the image itself, but could potentially be determined based on the design of the room and the surrounding environment.
