"Gisteren" by De Geest tells the story of a person reflecting on their past and how much has changed in their life. The lyrics talk about how the singer used to be a hero, but now feels like someone else. They feel disconnected from their old friends and feel like everyone is now looking out for themselves. The singer is unsure of where to go next and where they will find happiness. The chorus of the song repeats the feeling of waiting for things to pass and for someone they care about to forgive them and be there for them again, like things were in the past. The lyrics also talk about how things used to be so simple and how the singer wishes they could go back to that time when they were trusted and supported by their loved ones. Overall, the song captures a sense of longing for the past and a desire to make things right with those who were once important in the singer's life. It conveys emotions of regret, nostalgia, and a hope for reconciliation.
