Well, my take on it is that there are CM's throughout the Parks giving away things to unexpected guests....as part of the Year of a Million Dreams campaign. The items I've heard of so far ar Dream FastPasses, lanyards, ears....
A dream fastpass is given on a lanyard. Its a card that entitles the wearer to a fastpass to every ride where it is offered. There is no time constraints, you just have to use it on the day it is given to you. Once you use the card at a specific ride, they tear off a little tab that states the name of the ride. That's how they know you've used it.
