Your reality isn’t what you think it is—literally. Every sight, sound, and touch you experience isn’t a direct feed from the outside world but a carefully constructed illusion your brain assembles on the fly.

In their latest video, Kurzgesagt dives into the mind-bending science of perception, revealing how your brain blinds you for hours every day—and why free will might not be as free as you think.
