St. John Vianney

This might be a dumb question, but have you ever heard of St. John Vianney? I was reading about the saint and he was attacked nightly by the devil and even set his bed on fire (which we can see if you go to France as well as his incorruptible body). How does that happen? Can the devil attack all of us like that? Have you guys had any experiences like that? Is there a prayer or something I can do for St. John Vianney?
