it’s a cool thing your brain does called covert attention! wikipedia has better explanation than I could muster so here you go:
“Covert orienting is the act of mentally shifting one’s focus without moving one’s eyes. Simply, it is changes in attention that are not attributable to overt eye movements. Covert orienting has the potential to affect the output of perceptual processes by governing attention to particular items or locations… does not influence the information that is processed by the senses.”
