Himmelbett literally translates to "heaven bed" but refers to a four-poster bed, often with drapes. It evokes a sense of romance, luxury, and intimacy.
In the song, Beatrice Egli uses "Himmelbett" as the central image for a romantic escape with a loved one. It sets the scene for a dreamlike experience where they can be together,
Beatrice Egli sings a daydream about spending one night alone with someone in a "Himmelbett" (four-poster bed), a word that literally means "heaven bed", and the song takes that literally. She wants to fly "schwerelos durch Zeit und Raum" (weightless through time and space), to be "verliebt und vogelfrei" (in love and free as a bird), and to walk "barfuß auf den Wolken" (barefoot on the clouds).
The second verse pushes the fantasy further: from up there "die Welt, so fern und klein" (the world, so far away and small) shines in the moonlight, and "der Mann im Mond lädt uns zum Frühstück ein" (the man in the moon invites us to breakfast). The chorus keeps returning to the same plain wish, "Nur Du und Ich, das fänd ich wirklich nett" (just you and me, I'd really like that), which is Schlager at its sweetest: a date with "der Himmel, ich und Du" (the sky, you and me).
