Literally stepping into another’s shoes: The body-swap illusion

This is the body-swap illusion.

Nothing is what it seems, including our visual perception. We see through our eyes: well-cleaned panoramic windows overlooking the world outside. At least, that’s what our experience suggests. In reality, the window cleaner is only scheduled for tomorrow, the glass is terribly fogged up, and your eyes are more like raindrops that allow for occasional peeks into the outside world.

Our experience of colour is not in the world, but constructed by the brain.
