The process of soul fragmentation as one incarnates physically can be likened somewhat to Freud’s id, ego, and superego theories.
Since Freud did not take his hypothesis into prenatal development, there is no correlation.
He is remembered today mostly for his work on sleep, which tied the content of dreams to what the body senses during the night, decades before Sigmund Freud took up the subject.
Freud retold the episode at length in The Interpretation of Dreams and used it to frame the question of how much a dream can hold in a moment.

One of the first to mention this was Sigmund Freud, the founder of psychoanalysis, in his book Moses and Monotheism.
Basing his arguments on his belief that the Exodus story was historical, Freud argued that Moses had been an Atenist priest who was forced to leave Egypt with his followers after Akhenaten's death.
Freud argued that Akhenaten was striving to promote monotheism, something that the biblical Moses was able to achieve.
