In the ray diagram below (click to enlarge), the solid lines show the actual path of the light rays; the dashed lines show the path of the light rays projected by your brain. You see images where the dashed lines come together.
This ray diagram shows the rays that come from the front of an object and those that come from the back. After the first reflection, you see one image in each mirror where the dashed lines come together (1). After the second reflection, you see a second image in each mirror (2), then a third (3), and so on.
As you look at the images formed in one of the mirrors on the diagram, notice that there is an alternation of front and back views, that the images appear to be grouped in pairs, and that a front side is always facing a front side and a back side is always facing a back side. This corresponds to what you actually observe in the mirrors.
