Sweet Dreams (Are Made of This) was released in 1983 by British duo Eurythmics, formed by Annie Lennox and Dave Stewart, as the title track of their second album. Driven by its stark synth riff and Lennox's striking visual image in the music video, it became their breakthrough international hit. Decades later the hook keeps resurfacing in films, adverts and social media edits, where its mix of glamour and unease makes it perfect shorthand for ambition, fantasy and dreams that are not quite sweet.
