The song "Nightmare" by Handsome Ghost is about the complexities and confusion of a past relationship. The speaker is trying to make sense of their emotions and feelings towards their former partner. They reflect on how they used to move around a lot and how they wished they had just stayed in one place. The chorus repeats the idea that they are both just pins on a map, insignificant in the grand scheme of things. However, the speaker acknowledges that they're starting to care, which may suggest they are beginning to develop deeper feelings for their ex. The line "Say you're losing yourself, I think it's suiting you well" may indicate the speaker's recognition that their ex is better off without them or is finally finding themselves. Overall, "Nightmare" explores the complexity of relationships and how emotions can change over time, even if you thought you had everything figured out.
