No, they don't spin all the way around, but they can spin enough to make a person sense that kind of eye movement as spinning. This abnormal eye movement is called nystagmus. With nystagmus, there is a quick beat in one direction and a slow beat in the opposite direction. Naming the nystagmus and looking for patterns

is key in figuring out why the nystagmus is present.
