IMO, what CC means with “mindscape” he means “our best guess” based on “memory” of stored sensory experiential information. It is the “mind” that is translating exterior and interior electro/chemical experiences by producing a visual mindscape of what you brain is able to produce.
As posted elsewhere Anil Seth; “The Neuroscience of Consciousness” explains how the brain processes information and what it can do with that information. The pattern of consciousness.
