Breathwork class floor transitions to sand dunes

Pale studio walls reflect broad afternoon skylight across a room where resistance loops hang from low stools. A digital timer display glows softly near the edge of the floor, which abruptly shifts from smooth ceramic tiles to rippled sand dunes. The grains rise in gentle waves under the settling lamplight that pools in the corners. No people remain, only the equipment standing in the silence of early winter. The boundary between the indoor space and the outdoor dune texture is a sharp, impossible line cutting through the center of the room. Shadows from the stools stretch across both the hard tiles and the soft sand, anchoring the surreal transition in physical reality.
