Psychologically: She means the move of the front building to the house at the back, so a personal lowering and with it a social descent. Also cunning and crooked ways of the soul appear in it. Who wants to escape in the dream about backstairs, tries to squeeze in the awake life before a responsibility or to reach about a detour to the aim. This hidden stair also seems in erotic dreams and can circumscribe there a dubious relation. Popular: (arab).: you has a secret passion. (See also stair)
