A fanlisting is a list of fans for a particular movie, book, food, place, celebrity, etc.
In this case this is a fanlisting for WWE's Wrestlemania. Wrestlemania is the yearly Pay-Per-View the WWE has in March. And next year is their 20th anniversary.
Wrestlemania has been called the grandaddy of all pay-per-views. And like a good wine, it just keeps getting better and better with each passing year.
Why Dreams for the name? Well, it's the dream of every WWE superstar to participate in the main event of Wrestlemania. Because once you're in the main event? You've made it.
