The movie is about a girl who is upset so these Halloween people like ghosts and skeletons give her a key then she finds a locked door and sees the key so she goes in and sees all the people and she goes back everyday because they cheer her up and the parents don't know about it. The door to this magical place is under her bed. Does anyone know which movie this is?

Thank you

Kind of sounds like Coraline.. kinda (?)
