Begs the question, what really is vision / imagination / the mind's eye?
I read somewhere that you only "see" things which are useful to you, both physically and mentally. Like a door handle, or a chair when you're tired, or a person's microexpressions when someone is important to you. Kinda like that "ape in the middle of a ball game" experiment.
@torresjrjr certainly attention is a thing. I've been mulling over this a bit lately. I tend to think of the brain mainly as a control system for the body. basically a take off of embodied cognition. I haven't worked out what that means for the experience of vision--why it has these colors and shapes. it's not really useful but my answer to myself is something like, "what else would it be like to have these physical interactions with a thing like a brain?"🤷♂️
