According to Nico: The Life and Lies of An Icon, this song was one of two written for Nico's mother. Nico was quoted as saying that "One was for my living mother and one for my dead mother."
This was for Nico's dead and biological mother. The living mother could be about her aunt, who was still alive and who she did consider a second mother, or it could be a metaphorical term about her mother being alive in her heart.
