My view:
It should have been made clearer that Jessica (as agent for the Bene Gesserit) was teaching Paul Prana-Bindu—the ‘Weirding Way,” Thufir was teaching him Mentat, Duncan and Gurney were teaching him how to fight as well as military tactics and strategy, Yueh was teaching him science and philosophy, and Leto was teaching him leadership...In the scene in the stilltent, Paul’s line should not have been “You did this to me!”; it should have been, as it was in the book, “What did you do to me?” To which Jessica would have answered, “I gave birth to you,” instead of just crying and holding him, as she does in the movie. The fact is, that he was a tool of each of the adults in his orbit, all roughly pointing him towards a destiny as a great leader of men...they prepared him to be exactly what he became...because he was the tool that the Fremen needed to reach their goals…and indeed, he was the tool of the human super-conscious, which needed him to disrupt the patterns and mix the threads of human genetics...
And, indeed, Dune is undergirded by Jungian conceptions, such as the collective unconscious, or the supermind or whatever the proper term was...as an actual, functioning force in its own right, with an awareness of its own, and a purpose to mix the genes and move the flows of people into new environments to test those genotypes/phenotypes. Trained as he is for the mundane purpose of leading a Great House of the Imperium, the collective unconscious hijacks him to disrupt intergalactic society and force new mixing of the populations...because the Freman dream ‘just happens’ to coincide with the designs of the collective unconscious...
