What happens in the end of Labyrinth (the film)?

Sarah finds Toby and Jareth (Goblin King) tells her it's too late. She recites a quote from the book she was studying (at the beginning of the film), ans says "You have no power over me." She then ends up back at home and finds that Toby is safe, and asleep in his crib. She then goes back to her room confused whether or not it was all a dream. Whilst looking into her mirror, Hoggle appears, with Ludo and Sir Didymus. "Should you need us?" they ask. Sarah tells them that she still needs them in her life. They then appear to be in her bedroom. They celebrate together, and the owl (goblin king) watches from outside, and then flies away:)
