Constantine is attempting to play the song "I Heard it Through the Grapevine," originally recorded by Smokey Robinson and the Miracles in 1966. It became one of Marvin Gaye's signature songs when he recorded it in 1968, and another popular version was recorded by the rock band Creedence Clearwater Revival in 1970.

This is the first time Dream is referred to as The Sandman, the role from which the series itself takes its name. The original Sandman is a character from Western folklore who made his first literary appearances in stories by Hans Christian Andersen and E.T.A. Hoffman in the early 1800s, but would have been commonly known before that. He was said to sprinkle dream-bringing sand in sleepers' eyes; when you rubbed your eyes in the morning, it was this sand that you were rubbing out. He is usually associated with good dreams, rather than bad.
These lyrics belong to "Sweet Dreams (Are Made of This)", a 1983 hit by the Eurythmics, more recently covered by Marilyn Manson.
