False Awakening Suite.
Here's my logic.
1. We all know what a suite is, but a "suite" can also be a work that just includes extracts of a longer work. A suite would be particular good if utilized as an instrumental overture to an album, in which case it would have to be the first song.
2. Further more -- be patient -- I've long thought that if Dream Theater were to ever have a band anthem, it'd have to be an instrumental song, since singing about the Dream Theater or something like that would just sound goofy and random. If you look at the Falling Awake suite, it's about Dreams.
3. Which leads me to believe that the first song of the album "The False Awakening Suite" is the spiritual self-titled song of the self-titled album: the instrumental "overture" which is the Dream Theater anthem, the overture piece to an album which the band feel extremely confident as their best most representative music yet.
So, in other words, "The False Awakening Suite", otherwise known as "Dream Theater", the instrumental overture to the self-titled album
Dream Theater. Or something like that
