Trivia

 * The episode title may refer to:
 * The pun of "American Dreams", national ethos of the United States, the set of ideals (democracy, rights, liberty, opportunity, and equality) in which freedom includes the opportunity for prosperity and success, and an upward social mobility for the family and children, achieved through hard work in a society with few barriers.
 * There is also a name of a short-lived TV serial, American Dreams that run on 2002 - 2005.
 * The American Nightmare itself refers to various things, ranging from names of a band (former name of Give Up The Ghost), films, songs, to even a title of book that heavily critiques Sarah Palin (Going Rouge: Sarah Palin, An American Nightmare).
 * "American Nightmare" is a song by The Misfits. Writer Davy Perez tweeted a link to the song just before this episode aired.
 * Sam is revealed to be a fan of Lucifer's vessel, Vince Vincente.
 * When Sam is captured by the family and chained in the basement, he begins talking with the daughter Madga who is also chained. Sam discovers that she is chained because she has psychic gifts (telekinesis and mind-reading) and her inability to control her powers led her family to adopt the lifestyle of outsiders. Magda relays that her family thought she was a vessel for The Devil and kept her chained to protect the outside world. In trying to console her, Sam mentions how he had psychic gifts and those gifts didn't make him The Devil. This is ironic because Sam is the true vessel of Lucifer so his gifts did make him The Devil.

Quotes
Dean: So, Lucifer. The lord of evil, the angel of light, is now the master of butt rock. He jumped into Vince Vincente.

Dean: Cas is chumming it up with Crowley. They're hunting Lucifer together. That's right. One's an angel, one's a demon and apparently they solve crimes.
