There's a lot of imagery that implies imprisonment, such as these hands grasping for freedom.
Weirder, though, is the running theme of children and birth. There's the creepy kid in the halls...
...and all kinds of creepy things escaping through a mattress vagina.
There are also brief flashes of the Ten Commandments in neon, which implies that religion will have a role in the new season (and evokes just the right amount of Norman Bates).
