Freud's Dicotomous Uncanny

One of the themes which Freud touches upon is the two-fold relationship of the familiar and the unfamiliar. I don't remember where or if Freud said this in his Uncanny, but I found myself drawn to the thought of reflection. In essence, by seeing that which is foreign to us, what is repressed, the thought is being brought up within our minds. By coming in contact with that which we do not accept, it enters our minds, and becomes real. We become aware of something that may be within us, and although it is a foreign thing, simultaneously it is familiar, tucked within the recesses of our own minds. Because of this familiar possibility, we reject the unfamiliar, in order to rationalize that we are not the same as that which we reject. Repression, projection, other forms of defense mechanisms are all used to keep the image of ourselves high, while rejecting those that we do not desire to see within ourselves.
