I think the difficulty in recognizing such object relations stems from trying to do everything with a single positional system. Proposed solution: Start with a hierarchical container system at its most abstract. Let each object have a "position" in its container. The interpretation of the position is left to the container. The position can be a pair of coordinates meaningful in the plane defined by the room, or a triplet of coordinates in the 3-D space defined by the room, or (angle, distance, speed) relative to the room, which is the planet in whose gravitational field the object resides. The position could then simply be a string like "inside", "beside" and "above" to indicate the position relative to the container, without imposing the same system on the rest of the mud.
