If you are on the free to play build, you should not have access to dreams. Last f2p build did but that was by accident. 
As for getting a error after Game Over's, something got slightly messed up while fixing Azkim's stuff. The programming team has been informed and is working on it. For now, you should be able to hit "ignore" and continue on.
