It means are you aware that your mother is three-dimensional, that she has a dark side? Is she frozen in ice as if she was stuck in a particular image? Standing in the shadow is a reference to prostitution, in the second verse about the brother, to a street quickie. This is also the meaning of the cover to the single with the band in drag, some in WW2 drag. So in this way the song is a little like 'Walk on the Wild Side'. There's no point in going too deeply into the lyrics, which are impressionistic and surreal, not intended to be completely specific as to meaning.
