Those of us who study visual perception are aware that we can teach ourselves to look at the world as it really is, or as our brain sees it. Learning to see it as the brain sees it was through analytic introspection, referred to by E. B. Titchener as structuralism.
A good description of difference was described by JJ "Jimmy" Gibson years ago in this book, Chapter 3: The visual field(brain) and the visual world (mind):
Chapter 3, starting on p. 39
We are so used to living in a three dimensional visual world that we take it for granted, but there is normally almost no relationship between the information from the field vs. world in activities of daily living.
Given how different the two are, and how impoverished we are with merely a visual field as a source of information, it's not surprising at all to me that spiritual forces are always part of our reality.
