In the Pokémon movie "The Rise of Darkrai", Ash, Brock, Dawn, Tonio, and Alice encounter Darkrai in Alamos Town. Baron Alberto use his Licklilicky to fight it, but when Darkrai used Dark Void on it, it hits Ash instead, causing him to fall into a nightmare involving Darkrai itself. As the nightmare ends with Pikachu falling into darkness with Ash, he awakens to its Thunderbolt in a bed. When Ash asks the others and Nurse Joy where he is, Dawn replies: "The Pokémon Center."
I was wondering, how did Ash end up in the Pokémon Center and how long was he out?
