"Lay Me Down" is the 46th episode of Haven and the seventh episode of the fourth season, airing on Syfy on 25 October 2013. The episode shares its title with a 2010 Dirty Heads song, as well as a lyric from a 1994 Live song, both of which likely derive the phrase from the first line of the 18th Century children's bedtime prayer, Now I Lay Me Down to Sleep.
