Cover art for Reflection lyrics by As I Lay Dying

The Whole Album of Shadows are Security has a central theme of a placing too much emphasis on things that don't really matter, or things that will pass away. So this song seems to fit in as he's reflecting (see what i did there...the song's called reflection....it's clever, trust me) on a time in which he was really stressed out or depressed ("with mistaken guilt and shame"..... " against this endless ocean of self defeat") over something that he now realizes wasn't important.

some months are yet to pass puddles of ink surround this tired chair all of my sorrow has been spilled into my reflection

I think this is showing that time has passed, and that through writing this song (ink puddles) he's managed to get through it.
