It's an American coloquialism (at least I think it stems from here). Basically, "unreal" means something that is real, but is so good it seems like it can't be. So if you were to ride the best roller coaster you've ever been on, you might get off and say, "That was unreal!"I think I was able to grasp the whole WBann, except the words in bold. Could you rephrase that sentence?
