Imaginary Order or Register is a term used by Jacques Lacan to denote one of the three orders (or domains) of human subjective experience.
The other two orders are the symbolic and the real order.
The imaginary order (often called simply imaginary) is pre-Oedipal, while the introduction to the symbolic order and the Oedipal conflict are different aspects of the same process.
The imaginary is the order of our experience, dominated by identification and duality, it not only precedes the Oedipal conflict but also coexists with the symbolic order, even after the outbreak of this conflict.
