Perception is Reality

"Perception is Reality" is a 2018 post-punk song written, composed, and sung by Gilbert Martinez. The lyrics were written on June 12, and the music was composed on June 14. The vocals were recorded soon after.
The lyrics (as well as the song itself) are thought to allude to struggles with depression; they describe feelings of numbness and emptiness, alcoholism, allusions to death, and inability to reconcile reality. The song ends with the repeated proclamation, "This is my world."
The main chord progression of the song is as follows:
:Dm - B♭ - Gm - A
:i - VI - iv - V
This is a '50s progression in a minor key, with the A major chord containing the accidental C♯. However, one portion of the song near the end has the following progression:
:F - C - Dm - A
:III - VII - i - V
Again, the A major chord contains the accidental C♯.
==Trivia==
*The lyric "This is my world" inspired the title of the animated miniseries of the same name, also written by Gilbert.
*The music was inspired by the Joy Division song "The Eternal." Even Gilbert's vocals are reminiscent of Ian Curtis, which he attributes to their similar vocal ranges (they both sing bass-baritone).
*The song was written and composed during one of Gilbert's depressive episodes.
