There is also aphantasia [0]: the inability to voluntarily create mental images in one's mind. When people say to visualize or imagine something in their head, they actually mean that quite literally. These people can actually see visual images in their head. My understanding is that some people are also unable to control it, so when you say something they immediately conjure an image. In my case, I can take concepts and ideas and think about what it would be like to have that mental image, but I can't actually see it. It feels more like as if I were simulating having that mental image rather than actually having that mental image. I can add properties like sound or physics, but it has to be deliberate. My way of imagining things still lets me get easily lost in thoughts and daydreams though. I can hold the concept of a ball or cat in my mind without instantiating. My ability to conjure mental images is limited though. For example: with a concept of Tony the Tiger, even if I instantiate it I couldn't tell you how many stripes he has. When people talk about the heart or soul, they're referring to the "place" where their conscious experience happens. If you believe in dualism then it would distinguish between your soulspace and meatspace. If you don't believe in dualism then your soulspace is just a virtual space simulated within meatspace.
