War Inside My Head is about a veteran who's mind keeps drifting back into the days of war. The song goes on to tell that this soldier will never get rid of these flashbacks. The end of the song says that he is "tasting danger with each word I say." This part of the song is only about two minutes long and is the shortest part of the entire song.
The Test that Stumped them all is the next part. This part of the song describes a man who has schizophrenia. This part of the song has parts where the drummer, Mike Portnoy, provides noticeable backup vocals. I think they are hilarious. Portnoy has a deep voice so when he says those high notes the outcome is horrible. But that doesn't ruin this part of the song. This part of the song explains certain ways schizophrenia can affect those who have it.
The next parts of the song go on about different mental disorders and finally, in the last section of the song, titled Losing Time/Grand Finale, the song comes to an end.
