This song continues the space narrative on A Moon Shaped Pool. Thom uses metaphors of a UFO and extraterrestrial matter in order to portray the questions and darkness of humanity.
The song is also personal for Thom. In parts, it seems as if he’s speaking directly to a woman in his past. The woman could be Rachel Owen, Thom’s former partner of 23 years. As theorized in “Daydreaming”, 23 years marks “half” of Thom’s life.
