* For anyone living in a deep gravity well, this is true when "outside" is considered to be relatively flat empty spacetime - for Earth compared to interplanetary space, it would be a tiny difference (but non-negligible still; GPS satellites have to correct for the fact that stuff happens faster at their altitudes) [[hottip:*:Earth lags interstellar space by a little less than 2 seconds per century]], but if you were living just outside a black hole, it would be a very prominent effect.

* ''Series/{{Stargate SG-1}}'', the phrase "time dilation bubble" gets bandied about a lot. Probably best remembered in the fandom is [[spoiler: "Unending": ''50 years'' inside, about... 3 seconds outside. And they [[TimeTravel undid those 3 at the end]], too.]]

* In an Al Brodax {{Popeye}} cartoon, Popeye is in a space capsule helping test out one's endurance during sixty days in it. After losing his cool after hear Brutus (in a recording) gloat, Popeye sets off cans of aerosol spinach which launches the space capsule skywards at sixty times the normal speed while causing everything on Earth to go backwards. Brutus' time with Olive turns out to be all for naught.

* In SuperRobotWarsZ 2: Saisei-Hen, The location of the GetterRobo Armageddon Nuke Event is now on the Dark Continent. Gurren Lagann and Getter Robo participate because both series contain characters that need to age drastically, in a way that can't happen in a year like the others. ? The dimension quake will cause almost a decade to pass inside the Dark Continent until the seal reopens, while a year passes on the outside.

* AdventureTime: In the episode ''Puhoy'' [[spoiler: this happens to Finn. He goes to a pillow world, grows up, gets married, and has children. After he dies, he wakes up again in his own world a few minutes later, and begins to tell Jake about [[AllJustADream a crazy dream he had]]. A phone call interrupts him, and Finn totally forgets even having a dream...if that's what it was in the first place.]]

** In his CthulhuMythos short story "A Colder War", a US minisub returns after spending a couple of days traveling through a PortalNetwork set up by ((Precursors}}. The crew are dying of radiation poisoning and the protagonist notices they've also acquired grey hair and wrinkles.

* HalfLife 2 mentions off-hand the existence of several dimensions and how time and space works differently in each. Freeman's non-aging from the end of events at Black Mesa till the events of Half-Life 2 is probably because he was put in one of these dimensions by the G-Man, where Freeman decided to take a nap.

* In ''LightNovel/HaiyoreNyarkoSan'', Luhy Distone has a door in her apartment that connects to [[Anime/DragonBallZ the Room of Spirit and-]][[YouWannaGetSued *achoo!*]]. In the short story and OVA episode "How to Defeat a Kind Enemy", she spends one month (two hours real-world time) training Nyarko to become a MagicalGirl, mostly by [[DrillSergeantNasty channeling the spirit of]] Creator/RLeeEremy in ''Film/FullMetalJacket''.

* ''Film/{{Inception}}'': An hour-long dream spans five real life minutes. [[DreamWithinADream But a dream begun within that dream can last an entire day.]] [[MindScrew Start another inside that and it will last a year.]] [[AndIMustScream If you're stupid and/or desperate enough to go even deeper, get ready to spend at least a few centuries with nothing but your nightmares for company.]] This is demonstrated in the film when Dom and Mal are trapped in limbo for fifty years, waking up only a few hours after they fell asleep when they finally escape. There's drugs that make that gap even wider, turning a ten-hour dream into a week-long trip.

* In Joe Dever's ''LoneWolf'' and ''World of Lone Wolf'' books, years pass in Magnamund over the course of days spent on the shadow plane of Dazhiarn.

** In the ''Series/BuffyTheVampireSlayer'' episode "Anne", Buffy visits a Hell dimension where time runs much, much faster than on Earth. Angel is himself trapped in a similar Hell dimension at the time.

** A similar tack is used in other fanfics that merge G1 ''Franchise/MyLittlePony'' canon with G4's, such as ''A Mighty Demon Slayer Grooms Some Ponies'' and ''History Repeats''.

* ''TheChroniclesOfNarnia'' allow you to spend years in Narnia and return to your original age when you go back to Earth.
** You also return the same moment that you left.
** Time passage within Narnia doesn't seem to follow a pattern compared to our world; a year in the real world can take as little as 3 years of Narnian time, hundreds of years, or even thousands. Justified in that the children are summoned to Narnia only when there is great trouble, and thousands of Narnian years can pass before there is any.
*** In ''The Last Battle'', Prince Tirian has a vision where he sees all the Friends of Narnia in the real world, sitting around a table. When Jill and Eustace show up, they told him that dinner where Tirian appeared (and they saw him) took place nearly a week ago, while Tirian said to him it was scarcely five minutes ago.

* OlderThanRadio: The German legend [[http://www.kellscraft.com/LegendsRhine/legendsrhine082.html ''The monk of Heisterbach'']] uses this to illustrate the endless power of God. There's also a more dramatic poem by the romantic writer von Königswinter.

* AccelWorld provides a purely mental example. The Brain Burst program speeds a users thought processes by a factor of a thousand. The Unlimited Neutral Field essentially transports the users to an alternate world based on the real world for an indefinite period (as opposed to normal, limited duration battles). Its implied that high level players such as the Kings of Pure Colour have spent enough time there that their mental ages are considerably older than their physical age.

* In ''Manga/{{Naruto}}'', Itachi's Tsukuyomi has the ability to do this from a perception standpoint, causing its target to experience days' worth of illusions in mere seconds.

* In ''Manga/DragonBall'' several of the main characters use the "Room of Spirit and Time" (Hyperbolic Time Chamber in the Funimation and Ocean dubs) to squeeze a year's worth of training into a day. Only two days of training per person are permitted, or else the way out will vanish forever. This becomes Less of a problem later on when anyone Super Saiyan 3 or above is powerful enough to shout their way out. Which is to say they can literally ''yell so loud it creates a hole between dimensions''.

* Parodied in ''WesternAnimation/TheSimpsons'' episode "The Fight Before Christmas".
