Here's a good example,
The camera angle on the right is different, right? The lines in the pavement diverge from some point on the lower left?
Nope, the two pictures are absolutely identical. The reason most people think they're not identical isn't because of our senses, per se, it's because of how our brains interpret what we sense. We can't separate the two, because what we see is what our eyes collect
that is processed by our brains.
The "big moon illusion" is another good example. Nearly everyone is convinced that a low full moon near the horizon is much larger than full moon high in the sky, it's a common human experience that has generated much poetry and many lyrics to songs. But it's not larger, instruments prove that. We still don't really understand why our perceptions are wrong.
