Your expectation doesn't match real life! Try it with a window. If you bring your head closer to the window, your FOV increases, ie you can see more of the scene outside the window.

But there is no window. There is a box with a dragon in it. When I bring my eyes closer to the box, I expect to see more of the box, and more of the dragon. You can try it with any real box; substitute any appropriate object for the dragon. Pick your favorite 3D environment that features walls and dragons; notice how both grow, covering more of your FOV. This is what I expect to see as I draw closer to the screen.
The screen is the window.
