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 All Just a Dream, Fake Memories, 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 Weirdness Censor from an Agent Scully who actually does know better but just won't admit it to herself. Maybe because a deep wish for Brain Bleach has turned her into a Consummate Liar. In either case, heavy doses of Double Think may be applied.
This is frequently a side effect of Amnesiac Dissonance. Amnesia Danger often follows. Compare That Man Is Dead, where someone remembers their past but has moved on to a new life and wants nothing more to do with the old one.
- In Justice League of America, 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.

Cue Alan's frantic search for the truth about his memories.
- Happens in 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.
- In the movie Mary Poppins Returns, Jane and Michael, now grown up, talk about how they used to pretend their nanny took them on magic adventures. But it was only their imaginations... right?

- In Unicorns of Balinor, this trope is used to hide the princess of a Magical Land from her enemies. Loyal vassals erase her memories magically and smuggle her onto Earth, claiming to be her family. When she wakes up in a hospital, she knows things don't feel right, but she can't disprove their story that she was in a car accident. The princess reclaims her memories eventually, but a big part of her character arc is the fear that she might not be herself again if she remembers. A fear that is entirely baseless.

- The Philip K. Dick story "We Can Remember It For You Wholesale" (heavily changed for the 1990 movie adaptation Total Recall (1990).) The protagonist's vivid fantasies of being a secret agent on Mars lead him to request that Fake Memories of the 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. Then the company tries layering over the now returned memories with an even more grandiose childhood fantasy he had about saving the world from an alien invasion with compassion. Turns out that really happened too.
- The demotion of memories is a core function of the "Prosedür" in 7 Yüz. The procedure doesn't erase Banu's memories of dating Rıdvan, but rather displaces their significance. The memories are still there — they just aren't as important or emotionally relevant to her.
- In Buffy the Vampire Slayer, 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.

- In Smallville episode "Labyrinth", Clark wakes up in a mental hospital with vivid memories of being a superhero who has saved countless lives. However, the staff insists he's severely schizophrenic and the memories are his mind's attempts to feel safe and special. None of the powers he thinks he should have work and kryptonite is harmless. Confused, Clark slowly starts to believe the staff, but one patient, John, urges him to refuse treatment or it will allow Dr. Hudson, a phantom zone escapee, to take control of Clark's body and powers. The only way to regain control is to kill Dr. Hudson. Clark must decide if he really has superpowers and needs to kill his psychiatrist or if he actually needs to be treated for a schizophrenic break.

- Vampire: The Masquerade - Bloodlines: If the player takes Heather Poe on as The Renfield and later sends her away to live a normal life, it breaks her heart, but a Malkavian PC can use their Dementation power to convince her that her supernatural experiences were All Just a Dream. It's a bit of Video Game Caring Potential since it lets her remember the PC happily rather than be haunted by her knowledge of the Masquerade.
