Interpretations:I Am Alone
This song is interesting in that the way I interpret it makes it a very very dark song. Let me explain
To me, the song seems to be about a man who's about to shoot himself talking to himself in the bathroom mirror. In the song it sounds to me like he's personifying his mixed emotions by applying them to his reflections. The pov in this song is of the part of him that doesn't want to die trying to convince the part of him that does want to die to not pull the trigger. Hence the whole "lower our weapons" thing.
As he's trying to convince the depressed part of his brain to not shoot, he does this in a rather jovial manner. and to fit the narrative the man has put together in his head, all of this takes place in a setting you'd see in a James Bond film or something of the like.
There is so much spy imagery in this song that it makes sense to look for an interpretation within that genre, and there's a good one, IMO. There's a scene in Goldfinger where Bond get's "outfoxed" in a car chase, by a group of mirrors that makes him think he needs to stop to avoid a car crash. I suspect there may be a different, but similar Bond scene where he is searching, with raised gun, for a bad guy his apartment or such, and simply is suddenly surprised by multiple views of himself in a folding mirror. (If anyone knows of such a scene, let us know.)
The lyrics quite clearly fit with such a scene, but they also lead to the realisation "I am alone," which though reassuring in the context, is the kind of philosophical realization that can be pretty unnerving when you dwell on it -- very Linnelian, if you will.
If you think that Montana is a leg, and if a group of flowers on the side of a mountain seems to you like they are spelling out a message, then you might think that person in the mirror is a stranger (danger! draw a gun!) or your brother. Linnell must have an encyclopedia of psychological disorders that he keeps as bedside reading. --Nehushtan (talk) 18:58, 26 September 2019 (EDT)
Loneliness translated into absurdity
I think this song is about a lonely person looking into a 3-way mirror, maybe contemplating it but the song makes it seem absurd-silly by turning it into them singing about spy movie-related things.
