▨ sensations from anywhere

"We don't just sense what we see, feel, touch, etc.; our sensations might arise out of interactions among neurons anywhere in the brain." ... (source section 'Mind')

"we experience our thoughts about objects and the like in the same way we experience sensations" (source section 'Intentionality')

"Why would the brain feed us sensory images that are 'not real' (that is, not caused directly by external sensations)?" (source section 'Mind')

Reflections also feed such images.
