Cover art for Specular Reflection lyrics by Between the Buried and Me

I'll do my best with what I got from this.

This continues the story told by Swim to the Moon.

Prospect 1: He landed on a desert island, happy to be away. But eventually he misses society, in spite of its imperfections. There's inhabitants that do like... experiments on him. And he wants to 'wake up.'

Prospect 2: He wakes up. Leaving society was just a dream. He's incredibly confused, but has a plan.

In prospects 1 + 2, he's reflecting back on himself and wanting to change, because he's discontent with his life in either scenario.

Song Meaning

My interpretation is different. Similar to Sun of Nothing and Swim to the Moon (alkongside alot of their other lyric's), both these characters, particularly prospect 1 are tired of a repetitive society, so in a way your desert island refers to their inability to connect too their respective societys. Since this and the upcoming full length album are going to be concept albums, i think we cannot make comnplete judgements about this song yet because so much is yet to be built for these characters platforms.

Also the spacey/sciencey names of the songs (alongside the album name parallax) suggests to me...
