Although not officially released as a single or included on the original soundtrack for the film at the time, "Nightmare" has become a cult hit among horror fans and is one of Knight's most well-known and signature songs.

The following year, she was chosen to replace Patricia Arquette in the role of Kristen Parker in the film A Nightmare on Elm Street 4: The Dream Master.

Before production wrapped on The Dream Master, Knight met with director Renny Harlin and pitched the idea of writing a song for the film.

The camera pulls back from the Elm Street house to introduce Knight's character, and the song fades into Charles Bernstein's score from the original film.

In 2015, it was announced that the song had been remastered, remixed, and rerecorded, and is expected to receive an official extended play CD and digital download release before the end of the year.
