Uneternal Sleep is a song from Silent Hill 3 and is track 23 in the Silent Hill 3 soundtrack. The song was composed by Akira Yamaoka. It plays once Heather Mason has descended into the "core" of the Order's chapel and witnesses Valtiel assist the birth of God.
The song also plays in a 16-minute preview of the ghost story "Inescapable Rain in Yoshiwara," a disc that was included in the Japanese release of Silent Hill 4 soundtrack.
The song reappears in the Silent Hill film. It plays when Rose Da Silva's wound caused by Christabella starts to heal, ends when Alessa's revenge starts.
