There is no first moment of mirror reflection but a graduated series of understands at different levels of interactivity. You put on self-consciousness and it seems like the best thing ever. Once you are in there is no way to get out, but did you ever really go in? This is something that occurred inside original unreflective consciousness which was never left behind, there is no thing that could have left it behind. In order to maintain its ongoing experiencing it must continually fall back on original consciousness and consistently misrecognise it.
