Define "actual experiences". Normal people can not imagine an object like a red apple and actually see it, same as if one existed right in front of them. They can "visualize" it (just like you, it sounds), as in they can think of what it looks like, they would recognize one, they can even imagine broader scenes involving this apple (like an entire grocery aisle) but there is no "actual experience." You couldn't walk straight otherwise, you'd constantly be dodging imaginary objects that you'd be seeing.
