From nocturnes and nightmares to dreams and dances - music loves the night. Tom discovers the music and sounds found after the sun sets, from Wagner and Mozart to Faithless and Aerosmith via the songs of nightingales and crickets.

He explores the nocturnal sounds of the natural world with sound recordist Ellie Williams and sees how composers like Bartok have tried to incorporate those sounds in their music.

Music is full of dreamscapes as well as nightmares, so science writer Alice Robb is on hand to explain why we dream and how we might be at our most creative when we close our eyes to dream.
