If the brain can “fill” the gap when we move our eyes, like the “longer second” phenomenon, can it be the source of weird stuff we think we see sometimes for a split second?

Question

Like when you feel you saw something pass by for a fraction of a second, or an unfamiliar person looking like someone you know for a split second.
Thanks!

An important one is the empty road that our brain hallucinates – as your eyes flicker across the landscape (in movement called saccades).

We don’t see the motorbike that has zoomed into view, our brain just assumes the road is clear and isn’t really looking for all unusual details.
