A new view of Freudian theory

When I trained as a social worker at Leicester University in 1969 I discovered for the first time the theories of Sigmund Freud.  He was an Austrian neurologist, and founded all kinds of theories about human psychology.  His work was utterly brilliant, bearing in mind the fact that it was taking place around the turn of the twentieth century. He died in 1926, and therefore knew nothing of the explosion in neuroscience that has taken place in the last hundred years.

Freud's work was based initially on his in depth study of just a few cases - no more than six- and a great deal of long hard thinking about what was going on in the mind of his patients.  Then he began to examine his own psychology. Unfortunately for his followers however, many of these ideas proved to be just to difficult to accept, so they broke away and formed their own theories. But Freudian theory remains as the foundation of psychological thinking, even today. 

But what if we introduced the womb twin survivor hypothesis  and prenatal psychology into the picture?    Would Freud have thought differently if he knew as we now do, that all pre-birth experiences remain in the mind as a template for all future life choices? What if he knew that he was living out his own Dream of the Womb as he sat for years, constantly smoking and giving himself terminal cancer, while thinking about what was going on in the minds of his patients?
