coconsciousness
A technical term in psychology and philosophy referring to a secondary or parallel consciousness alongside the primary one. Rare in everyday language.
The concept of coconsciousness is used in some psychological theories.
潜在意識 is 'subconsciousness', which is below the threshold of awareness, whereas 副意識 is a co-existing conscious state.
Compound of 副 (ふく, 'secondary, auxiliary') and 意識 (いしき, 'consciousness'). The exact origin is uncertain, but it likely arose as a translation of the English psychological term 'coconsciousness'.
