Do you self-identify the movement through personal proprioception? Or is it completely disconnected from yourself, like a set of poltergeists dorking about in a nebula?
I can "visualize" motion with proprioception (e.g., imagining the motion of fingers opening and closing, but I don't actually see a hand) but also without any proprioception. Like, seeing the motion of a non-specific object bouncing around a box.
Try it!
