Have you ever imagined that we're actually in four-dimensional space, but our bodies' ability to perceive it hasn't yet developed? We can't sense it. It's like drawing a three-dimensional figure on a two-dimensional plane. When you become immersed in the illusion of the 3D image, you place your perception in a two-dimensional world. There, you can see and understand a higher dimension, but only because you're situated in the two-dimensional world. However, when we step out of this three-dimensional illusion and regard the image as an actual two-dimensional picture, our perception reaches the three-dimensional world: the world you and I now inhabit.
