Shadowy pervaded in Nachträume the lied "Nacht und Träume" by Franz Schubert is latently present. In also 29 bars and in the same slow tempo the harmonic material is preformed by way of intimation with floating ad libitum articulated text by Collin, while a searching introverted melos finally flows into the introduction of the lied. Perhaps: a prelude of the prelude ("Nach-träume"), perhaps: a paraphrasing meditation ("Nacht-räume"), perhaps: a reduced and frequent "Kehre wieder!"
