Our culture in the twentieth century has a tremendous collective prejudice against the imagination. It is reflected in the things people say: “You are only imagining things,” or, “That is only your fantasy, not reality.”
Conflating opinion with imaging. Opinion is terminal, a schematic response and largely habitual whereas imaging is active and the direct internal analog of playing. One learns nothing new from one's opinions whereas is fraught with potential. Of the two, imaging is the closer approximation to "reality".
