Can blind people imagine?
People that are blind from birth have never had any input to their visual cortex, so they have no way of imagining how something “looks”. They can know the shape of how something feels (like a ball), but they can’t ‘visualize’ the shape of a ball because the part of the brain that does that has never been used.
