I pondered the same thing. It seemed like a nice way of kind of tapping MP on the shoulder after him hearing an epic album, and being like "Hey listen to these lyrics, does this remind you of yourself?"
"And I came to forget, why I longed to be so close."
^^Mike Portnoy kind of forgetting why he longed to be close with the members of the band, but instead wanted to break away?
"And then, one day I, stopped caring"
^^How he stopped caring about the band, and wanted to move on?
Nuggets? You decide.
