Written by John Lennon and sung by Ringo Starr, the track aims to provide comfort and peace as it offers assurances of a good night and sweet dreams. The key themes revolve around love, comfort, and the tender, soothing presence of a loved one. Particularly poignant moments include the repeated refrain 'Good night, sleep tight,' which emphasizes a sense of safety and warmth. The orchestral arrangement and soft, calming melody further enhance the tranquil and reassuring nature of the song.
