It can also vary depending on the subject to be imagined. For some people faces, especially familiar ones, I can see their faces in high detail (flaps of their noses, even pockmarks and other texture). The "picture" doesn’t stay still and it sometimes requires effort; though some imagery comes unbidden and effortlessly. Other topics I have a harder time with and are more abstracted. The problem with discourse at this level, however, is how subjective it is: when I say I can picture in my head the beautiful outdoors scenery of my last vacation, how accurate is it? If you could download a hardcopy from my brain, would you tell me "this doesn't look like a photo at all"? But what if I'm actually there, watching with my eyes -- is the image that forms in my brain accurate? Maybe someone would also scoff at it if they could download it, "this isn't what the scenery looks at all!". I fear we will never be able to solve this riddle.
