You just contradicted your self there. So what do you want? Again?
As you know, the skybox is in the shape of a
box. Which means there's a "ceiling" and "walls" since a sky
box is a
box and has sides. But you can't actually reach the ends of the sky
box as it's only for aesthetics, so what he wants is the
walls to be the bedroom's walls, and the
ceiling to be that of the bedroom's ceiling. So it's like a infinitely huge bedroom.
