Neither the ancient Greeks nor the ancient Chinese had video recording or even photography, which seems to be the metaphor that allows people to explain what they do or don't have.

I must have relatively weak mental imagery? I can imagine seeing an apple, or recall the visual memory of my fruit bowl, but I'm hard-pressed to extract any definitive visual information from it, like I could if I really was looking at it. I'm visualizing the fruit bowl, but how many apples am I visualizing exactly? If I decide I'm visualizing two, now I've lost the relationship between the banana and the orange. I can see the Mona Lisa, but where do her arms go, actually? Maybe sort of crossed somewhere? What's going on behind her, some kind of green-brown pointy trees? Nope, there's her cheek again and some paint cracks. It's less like looking at a picture and more like dreaming of one.
