Alice used to be something great, or at least be a part of something great. For example a queen or a wizard, or a friend of either. She still remembers it, but she no longer believes in it. Instead she has demoted her memories to the role of something lesser. She keeps telling herself that it was AllJustADream, FakeMemories, insanity, overactive imagination, whatever...

Note that the greatness doesn't have to be a good thing so she might have good reason to pretend it never really happened.

In either case, her past is likely to catch up with her one day...

Sometimes a kind of retroactive WeirdnessCensor from an AgentScully who actually ''does'' know better but just won't admit it to herself. Maybe because a deep wish for BrainBleach has turned her into a ConsummateLiar. In either case, heavy doses of DoubleThink may be applied.

This is frequently a side effect of AmnesiacDissonance.

* In ''Starborn'', the hero initially believes himself to have invented an entire Sci-Fi setting. However, it's actually his real background. He knew that as a kid, but his earthly foster father talked him out of believing such nonsense.
* In ''JusticeLeagueOfAmerica'', when the league defeats and captures the White Martians, they consider sending them to the Phantom Zone, but Martian Manhunter instead decides to use this punishment. The White Martians are soon given mind-wipes and mental blocks that remove all memory of who they really are and given the lives of normal humans. Manhunter's dialog suggests that this was a common punishment on Mars for particularly heinous crimes.

* This ended up being the one of the main plot devices in ''Film/TheFinalCut''. The film opens with Alan's memory of him causing Louis to fall to his death when they were both kids, but when going through the memories of Charles Bannister, he finds a man who looks like Louis. Cue Alan's frantic search for the truth about his memories.
* Happens in ''Film/{{Hook}}'': Peter Pan grew up in the real world and refuses to believe that he used to be Peter Pan, even when Captain Hook leaves him a note. Justified in that his adventures were actually recorded in the form of the Peter Pan mythos we know so he could more easily write it off as something he just picked up or read about.
* Late in the film ''Film/TwelveMonkeys'', Cole starts to believe he really is just an escaped schizophrenic and not a time-traveler.

* The Creator/PhilipKDick story "We Can Remember It For You Wholesale" (heavily changed for the 1990 movie adaptation ''Film/TotalRecall1990''.) The protagonist's vivid fantasies of being a secret agent on Mars lead him to request that FakeMemories of same be implanted by a company that does this as a sort of virtual vacation. Except that the fantasy turns out to have been actual memories due to an incomplete mind wipe. [[spoiler: Then the company tries layering over the now returned memories with an even more grandiose childhood fantasy he had about saving the world from alien invasion with compassion. Turns out ''that'' really happened too.]]
* This seems to be happening to Kinbote at various points in ''Literature/PaleFire'', though it really picks up near the end.
* In ''Literature/TheChroniclesOfNarnia'', Susan gradually develops a refusal to believe in her own life. In [[TheLastBattle the last book]], she refuses to believe that any of her adventures ever happened. This saves her life, which is not a good thing in [[HeavenSeeker this kind of setting]]: she's left behind on Earth while everyone else go to heaven to be [[PalsWithJesus Pals With Aslan]]. Her disbelief is a very drastic step, considering she spent at least a decade as queen of Narnia. After leaving Earth the first time, she practically grew up in Narnia. While an immigrant, it is her home as much as England is. So, why does she disbelieve her memories? Well, there are two ways to interpret the situation:
** The narrative solution: TheLastBattle is very much an AuthorTract against the faithless and people who abuse religion to further their own ends. Susan is the StrawLoser for the "people who have abandoned their faith" category. This impression is reinforced by how no other characters try to understand her. Instead, they simply dismiss her as a shallow idiot who has taken a [[FaceHeelTurn Face Bimbo Turn]].
** The psychological solution, considering the FridgeHorror of the series (and thus, an AlternateCharacterInterpretation): for a character in Susan's position, it's quite realistic to be so emotionally traumatized that she tries to flee from her memories and pretend none of it ever happened. In the second book, she and her siblings got dropped into another world and drafted to be ChildSoldiers. After surviving the war she became queen, spending the rest of her youth as royalty of her new home country. Then as an adult, she's suddenly cast out of her new home and reverted to childhood. When she get sucked into Narnia again (quite painfully, and as always without her consent), it is a land ravaged by brutal oppression. She is again forced to become a ChildSoldier, suffering through the horrors of war. When the dust has finally settled and she has done her part, she is again cast out - and this time informed that she will never be allowed to come home again.
** In fact it's much simpler than that; Susan is social minded and trying to fit in with her crowd, pushing memories of childhood wonder aside are part of that. According to Lewis his point was that we are free to turn away from Grace. He further said that Susan might well return to Narnia someday, in her own time and her own way. Susan has ''not'' been 'cast out'. It is ''she'' who has cast Aslan and Narnia out of her life but she retains the option of inviting them back in. 'Once a Queen in Narnia, always a Queen'. The choice is entirely her own.
* In ''Literature/HarryPotter'', Aunt Petunia is portrayed as this trope. [[spoiler:Then it's revealed that she has simply been lying, pretending out of spite to not believe in magic.]]
* The Pat Cadigan short story "This is Your Life (Repressed Memory Remix)" involves a [[PsychoPsychologist therapist]] trying to convince a woman that her happy childhood memories are a cover for RepressedMemories of her father sexually abusing her. The ruse has already worked on her brother.
* In ''Literature/ThreeHeartsAndThreeLions'', engineering student Holger Dansk is troubled by odd memories and half-recalled dreams of another place. It takes a near-Death experience when fighting for the Danish Resistance to trigger the truth: he is really the Danish take on King Arthur, recalled to life in a strange otherworld to fight for the soul of his country against alien invasion.

* In ''Series/BuffyTheVampireSlayer'', this is the fate the demon of the episode "Normal Again" had in store for Buffy: she would be tricked into killing all her friends and then spend the rest of her life telling herself that they never existed and that she was never the slayer. That all her memories of Sunnydale was made up in her own head while she was a psychotic living in a mental institution.
* An episode of ''Series/{{Charmed}}'' has the same plot as in the above ''Buffy'' example, with the addition that if Piper falls for it, the demon can steal her and her sisters' powers.
* Variant: Toward the end of ''{{Series/Dollhouse}}'', [[spoiler:Echo]] seems to prefer retaining [[spoiler:her]] composite identity to the possibility of regaining the memories of [[spoiler:Caroline Farrell]] despite that being the original memory and personality set.
** Done more directly with [[spoiler:Senator Daniel Perrin]]'s shocking discovery that [[spoiler:he]] is actually a "doll" with altered memories.
* This turns up in ''Series/DoctorWho'' series 3, when the Chameleon Arch makes the Doctor and [[spoiler:the Master]] [[BroughtDownToNormal human with a false identity]].

* In ''{{Kult}}'', this is a core part of several recommended character backgrounds. The character starts out as a normal human with a denied supernatural or at least abnormal background.

* In ''VideoGame/ViceProjectDoom'', this starts to crop up a lot as the plot progresses.
