Have you ever had a dream where you dream about a person you know? In the dream you are consciously aware that the person you are dreaming about is the person you know. Your mind registers this fact. But they don't look like the person you know, act like the person you know, and your dream self doesn't feel about this dream person in the same way that your real self feels about the real person.
And yet your dream self also knows all this. So, you struggle in your dream with two sides to your self. One side acknowledges that this person is in fact exactly who they should be, while the other side tells you that something isn't quite right with them.
