Yeah, when I first heard this I tried to picture an elephant. And I thought, huh. I can't. But I realised there's a vague, hazy representation of it in my mind. That idea of needing to see things with picture clarity really threw me at first.
Yep. I can picture things all right, even details such as surface texture, and if I'm eg. planning a route I'm certainly doing it in a visual way (imagining a map), but the sensation is much more "ghostly" and transient than real imagery. The same goes for other modalities like sound or smell or touch.
