I can picture things in two ways: I can picture whole scenes, or I can imagine something existing in my vision, like I can imagine a ball lying on the floor or I can imagine a painting hanging on the wall. In both cases the pictured thing definitely feels more internal than what my eyes are perceiving. So it’s not quite like I’m superimposing a floating object in front of me on top of my vision, it’s like a post-processing filter or something. It definitely doesn’t feel like my eyes are seeing whatever I’m picturing, it feels like it’s happening inside my head.
