Small aperture = Very deep DOF so the dust on your sensor is more visible.

Yes, that's normal. When you stop down, the light rays are more parallel, coming more from the center of the lens. That makes the shadows of the dust sharper, and easier to see. At wide apertures, it takes a pretty darn big chunk of dust to be visible.
