It does seem kind of misleading to ask someone to close their eyes to visualize something in their mind. It has nothing to do with your eyes.

I can visualize my house in my mind while simultaneously seeing whatever is in front of me. Though the “mind’s eye” description is apt because it is like seeing with a totally separate set of eyes that has zero awareness of my real eyes and sight.

It’s almost like remembering the experience of seeing it, or inventing a new memory of seeing it.

Does it? For me shutting out other visual stimuli makes it easier to visualize in my head. I can still do it with my eyes open but it feels less real, like a hologram in my head rather than imagining I’m seeing it in front of me
