A Bad Dream by Keane delves into the introspective feelings of loss, fear, and existential angst. Inspired by W. B. Yeats's poem 'An Irish Airman Foresees His Death,' the song captures the emotional turmoil of someone grappling with the anxieties surrounding life and death. Key themes include mortality, the search for meaning, and the struggle with inner demons. Particularly poignant moments are found in the haunting chorus, where the singer repeatedly reflects on life feeling like a bad dream, highlighting the sense of despair and disconnection from reality.
