It is rather the mother-imago that has turned into a lamia. The mother-imago, however, represents the unconscious, and it is as much a vital necessity for the unconscious to be joined to the conscious as it is for the latter not to lose contact with the unconscious.
Woodman argues that the mother-imago, when split from consciousness, transforms into a devouring lamia-force, and that psychological health requires their dynamic conjunction.
