Biconscious refers to a system with two or more consciousnesses, however this differs from polyconscious as the number of consciousnesses is less than the number of headmates.
Dualconscious is a consciousness a system can develop over time, or even have from the start of their multiplicity. The state of being dualconscious is when a system completely regresses back into the singlet state they had before they became or discovered their plurality. They will normally have none, or very few, memories of ever being plural while in this state.
In mirrorconscious systems, consciousnesses are fluid, and headmates can travel between them freely.
Consciousness is a concept with no one clear definition. It is often used to describe the presence of multiple simultaneous independent streams of thought within one body (as with polyconscious), or even the presence of multiple conscious/sentient agents within one body (as with multiplicity in general). It may also describe the level of awareness a headmate has of the outerworld, as is indicated by co-conscious.
