According to the motor corollary discharge theory:
When we move our eyes, the world moves as well. We know that we are moving
our eyes (the world is staying still), because when the sensory information
goes to the brain, the motor part that is moving the eye sends a signal
over (corollary) and basically tells the brain - hey the world isn't
moving, it's the muscles moving the eye. If no information is sent, then
the sensory information is sent to the brain that the world is moving and
it is not blocked by the motor information. So the reason why a person
experiences this is because no motor information is telling the brain that
the eye is moving, not the world. You can get the same thing by jiggling
your eyeball with your finger (lightly!!)
