The song "Invisible" by Gabrielle Aplin explores themes of feeling unnoticed and unseen in a relationship. The lyrics depict a situation where the narrator feels like they are not being recognized or understood by their partner. Despite trying to communicate their feelings, their partner dismisses any changes that may have occurred in their relationship. The narrator expresses their frustration at not being seen or heard, as if they have become invisible to their partner. They feel like their words and emotions are disregarded, as if talking to a wall. The reference to the ceiling and the floor represents how their partner's attention is focused elsewhere, rather than on the narrator. Throughout the song, the narrator acknowledges the difficulty of speaking up about their feelings and the layers of the relationship that have deteriorated. The repeated phrase "Now I know that I'm invisible" reinforces their realization that their presence and emotions are being overlooked. Overall, "Invisible" highlights the struggle of feeling unseen and unheard in a relationship, emphasizing the importance of communication and recognition from a partner.
