We learn facts in life from books or from experience, and we remember them. If later we ascertain a new fact about the same subject or phenomenon that contradicts the first impression, we can't erase that first fact, but we keep both facts with the ability to distinguish between them clearly, in consciousness.
For example Pluto used to be the 9th planet however is no longer. But if in a dream one tells someone tha Pluto is in fact the 9th planet, does this mean that there is inconsistency between the id, ego and superego?
Can we link this to slips of the tongue/mind or silly mistakes to which we later feel "oh I still knew it, I did that mistake"
