It has been explained Jasper physically alters the chemicals in the brain to make people feel what ever emotion he wants. He doesn't just make them feel an illusion. It is supposed to be why he can effect Bella's emotions because he is not trying to trick her brain with a fake emotion but actually making her brain produce the chemicals that make her feel these emotions.
