Yep, to some degree. It's usually called "getting lost in thought", and traditionally in movies and media someone else snaps you out of it by yelling your name a few times.
I liken it to people who claim they can visualise a photorealistic image right in front of them, superimposed over the real world (yes, I've met such people). If you ask them to visualize a black box that grows to take up the entirety of their vision, blocking everything else out, they have to admit that they can't do that. Because while they've identified what they're experiencing as "vision", it's not that. It's something else that kind of feels like vision, but they lack the language to articulate it.
