I analogize. I do it a lot. Helps me comprehend. Helps me explain. I see things regarding ideas, imagination, mind, perfection, ideals, etc as this: Lines on paper. But they are lines on paper in an optical illusion way: We see a line as straight that is drawn. Our mind may record lines as straight and perfect. But zoom in? Not perfect. Not 2D. Not even close. Yet, we manipulate the optical illusion lines very well in our minds; we have visual systems attuned to outlining. Helps us with viewing perspective and such. The "realness" or "realer than real" qualities that we tend to give this thing called "imagination" I think, is ultimately due to how we incorrectly process lines in our visual system. I believe the machinery is in there and it is used for ideas. Things move faster in the imagination because there's less bulky stuff holding it back. Even Time flows more freely in imagination, allowing us to travel freely back and forth through time linguistically without any issue at all, while our bodies lumber along as they do. I believe ideas are physically real but some of the machines they produce - like systems of ideas and such, always suffer from a major flaw: they're illusionary. Physically real in the way that our brains process lines and consider them 1D or 2D things... but not real in the slower world out 'here'.'
