A heavy song, written (unsurprisingly) about a panic attack. The lyrics are reprised in Intervals in the title track. The song is written in the key of C, to tie in with the concept of Octavarium. The interlude between this song and Never Enough is written in C#.
- The song is featured on the music game Rock Band 2, along with Constant Motion
