The subconscious and unconscious are different, and the subconscious has it's own working memory that the conscious can't access.
An interesting read is Daniel Kahneman's Thinking Fast and Slow that explains cognitive systems, 1 is subconscious and fast and the other is conscious and slow
All of this indicates the flaw in the account of “consciousness”. Consciousness is elemental and “conscious”’or “unconscious” are “state forms” both of consciousness.
Consciousness is the envelope. Conscious is a category of awareness.
My brutally downvoted comment implied this, with more conjecture of the envelope. Enable “show dead” if you didn’t catch it!
