Freud Tentative Answer

I found Freud a bit hard to understand and had to reread some sentences twice to think about it. From what I understand, the ego is the consciousness and controls what we express to the world, though there is some control from an unconscious force as shown by repression. When we approach the topic of a repression, our normal associations or responses fail but we can't really explain why; therefore, repressions are unconscious.  The ego is the common sense and reason, using perception, while the id is the passions, using instinct. This reminded me of the noble savage again (Rousseau). I'm not sure if it was Rousseau or Smith or someone else who said this, but someone in this past semester had said that instincts work much better for the purpose of our survival than reason does. Though I think in Freud the instincts and passions refer more so to sexual desires (?). I was confused about the unconscious, conscious, and preconscious. I understand that consciousness is the surface of the "mental apparatus" and that it is the first point of contact to the world. The unconscious is material in our brains that we don't know about. The pre-conscious is "brought into connection with word presentations. What does that mean? Also, in the case of a déja-vu dream or just a bad gut feeling, which part of the -conscious would those be in? I'm looking forward to tomorrow's class to clarify these concepts!
