What do people mean when they say the can see the things they imagine? Do people mean they really see things in their mind the way they see things "in real life"?
Yes, imagined vision is "seeing with the mind's eye" and very like seeing. If I am really concentrating on something I am visualizing, I may see it with greater clarity than the actual sight provided by my eyes.
For whatever reason, I have a hard time visualizing faces, even faces I know very well. I believe this is part of a mild prosopagnosia. I find it strange because I can recall other visual detail very well. For example, if I were to imagine the salient difference between a Boeing 767-200 fuselage and an Airbus A320 fuselage, the details of shape, angle and proportion are easy to visualize. I could draw a somewhat accurate one from the one I can visualize. I can't do the same for faces.
