Mary Shelley’s Frankenstein psychoanalyzed, the monster that illustrated Victor Frankenstein’s relation to the author reflecting her real relation with the dead mother.
Psychoanalytic interpretation
Psychoanalysis is a theory that describes the human mind as an apparatus with three parts: innate needs, consciousness, and memory. Other ideas which have been ascribed to psychoanalysis include unconscious mental processes, repression, resistance, and centrality of sexuality.

Relationship between Frankenstein and the monster
Most comment that the relationship between Frankenstein and the monster embodies Shelley’s ambivalence towards her mother. Shelley lost her mother, Mary Wollstonecraft, in early childhood and was totally obsessed by the idea of the former’s neglect towards her and her becoming a murderer monster.

The monster as a metaphor
Other scholars believe that the monster is a metaphor for a motherless child, since Shelley was also an orphan who lost her mother.
The monster as a result of Victor’s lust
The monster is also interpreted as the result of Victor’s lust to recreate his fantasy of his imaginary mother. This attempt at bringing the imaginary mother within the bounds of the symbolic ends in failure and retribution.
