Can a bar of soap get dirty?

Technically yes, but it’s not something to lose sleep over. Germs do like to live on bars of soap, but they are typically washed away as you wash your hands. A few studies (which, keep in mind, were funded by soap companies) have been conducted on this matter, and no soap germs lingered on any of their participants’ hands.
To decrease the amount of germs on your soap, make sure it dries out between uses—bacteria like damp, slimy soap best. Also, if you rinse your soap before use, you can send many of the remaining germs down the drain.
