History Main / TheLonelyDoor

* The doors used by monsters to enter kids' bedrooms in ''WesternAnimation/MonstersInc''. These doors are each twinned with a specific location in the human world, but they need to be hooked up to special mechanisms to "work" as {{Portal Door}}s, otherwise they're just mundane pieces of wood. There is also a door used to [[ReassignedToAntarctica banish people to the Himalayas]].

* ''Manga/{{Doraemon}}'': One of Doraemon's recurring [[MacGuffin tools]] is the "Anywhere Door", which is a free-standing door that can bring you to any location you tell it, as long as you made sure you've [[LiteralGenie worded your request carefully]].
* ''Anime/DoraemonNobitaAndTheTinLabyrinth'' has the briefcase containing the Portal Door that leads to Burinkin, which manifests as a similar door in the middle of a beach.

* ''WesternAnimation/TheOwlHouse'' plays with the trope. Not only does it work the reverse of usual--the main character Luz goes through a normal door in an abandoned house before emerging from a free-standing one in the demon realm--but the door can actually be [[ImpossiblyCompactFolding folded up into a suitcase]] and moved to be reopened elsewhere. [[spoiler:Although after she destroys it, it gets rebuilt later as an immovable one in Belos's lair.]]

* In the third season of ''Series/OnceUponATime'', Prince Charming and Snow White need to visit [[Film/TheWizardOfOz Glinda the Good Witch, to learn how to defeat the Wicked Witch of the West]]. She has been exiled to a dark forest, where they find a door like this that leads to her prison. In a variation, the other side of the door is ''also'' free-standing, just in a beautiful winter forest, and while anyone can go through it, OnlyThePureOfHeart will reach Glinda; anyone else just comes out the other side still in the dark forest.

->''I found a door. An old oak door, standing unsupported by any other structure. I didn't know if it was an exit from the Dog Park or an entrance to something much worse, but... I went through it. Now I am in some old house...''

* In ''LightNovel/RestaurantToAnotherWorld'', the restaurant Nekoya's door appears in random places in various locations across the land, waiting to be discovered. Those who do discover the door usually build homes or shrines around it as the door itself disappears after the entering customer leaves through it and only reappears every seven days.

[[folder:Music]]
* In Music/LindseyStirling's music video for "Take Flight", a single door with lightbulbs hanging in front of it is seen at the end of Lindsey's journey. [[spoiler:The door leads back to Lindsey's own house.]]

** "WesternAnimation/OperationRabbit" starts with Wile E. Coyote placing a portable door outside of Bugs Bunny's burrow just so he'll have a door to knock.
