"Don't Close Your Eyes" is a heavy rocker from the 1984 album, Tooth and Nail. Co-written by Don Dokken, George Lynch, and Jeff Pilson, the song is built on a massive, driving main riff. Lyrically, it touches upon themes of anxiety and the fear of what lurks in the darkness, a theme Dokken himself has connected to nightmares and personal struggles. It is a powerful example of the band's metallic edge and features George Lynch's aggressive guitar work.
