Past Life Memories

Past Life Memories are memories that a reincarnated character gains from previous incarnations of their soul.

When Reincarnation and Past Life Memories are presented as being real within the context of a story, It often works in a way similar to Genetic Memory, by giving the character knowledge and skills that they would otherwise be unlikely to gain for themselves. Past Life Memories often manifest as Dreaming of Times Gone By. On rarer occasions, an entire identity from a past incarnation my start to emerge, resulting in a Split Personality. Sometimes a character will undergo a Split Personality Merge, with their current identity combining with that of a previous incarnation, giving them complete access to the memories and skills of the previous incarnation and resulting in a major Level Up.

In most works with Reincarnation, the majority of characters do not gain Past Life Memories, so having them is often a sign of being a particularly important soul, perhaps even The Chosen One.

Of course, in other works, Reincarnation is presented as not being true, and claims to having memories from past lives are treated as a sign of eccentricity or even insanity. A character making a claim to having Past Life Memories still invokes this trope.

Real Life public figures that can be verified as making claims to experiencing Past Life Memories are acceptable examples, as long as it is clear that these are claims only and this is not the place to debate whether or not these beliefs have any foundation in reality. Troper Tales should not be included under the Real Life heading.

Compare Genetic Memory.

Tabletop Games

• Exalted: The Spark of Exaltation (the godly thing that allows you to kick ass and chew bubblegum) attaches to the soul of its recipient, receiving the Exalt's memories in the progress. When an Exalt dies, the attached memory is normally removed by Lytek (the god of exaltation) because human souls aren't meant to house memories other than their own. However, the Sparks captured by the Yozis aren't purified this way, so a Green Sun Prince can draw upon the memories of the previous Exalt his or her spark is attached to, gaining sudden skill as a result. It has its dangers too: due to the potential depth and vastness of the tapped memories, the previous Exalt's personality might overwhelm the current, obviously-younger Green Sun Prince. An official example was a (male) Infernal letting go of an elder Sidereal instead of dealing the final blow, because that Sidereal was his/her husband in previous life. That's an override of gender, allegiance, and possibly sexual orientation.

Video Games

• The Nameless One can do this in Planescape: Torment.
• In Silent Hill 3, Heather occasionally has Alessa's memories, even before she discovers she is her reincarnation. Some of the memories might also be Cheryl's.
• A major plot point in Tales of Innocence.
• Shin Megami Tensei: Digital Devil Saga deals with this, although more prominently in the second game. To wit, in the first game, Gale has continuous flashbacks to a weeping woman. He initially chooses to use Emotion Suppression to deal with it, but eventually is forced to confront the memory. Later, it's revealed it's the last memory of the man whose personality Gale was constructed. The Four Archangels are a much weirder example - they're victims of the Demon Virus, who apparently have had their personalities obliterated by it and replaced by the consciousnesses of the Archangels Uriel, Raphael, Gabriel and Michael. The problem? All four make comments related to experiences the Archangels had in Shin Megami Tensei II, which apparently took place in another universe.
• Touhou: For Hieda-no-Akyu, it's one part this and one part Genetic Memory, as she constantly reincarnates into her own bloodline (like certain figures in Real Life religions).

Ellen was given memories of a version of herself from another universe to alleviate the stress of being an Opposite Sex Clone and, supposedly, prevent her from going insane due to how souls work.

• In the Exalted fancomic Keychain of Creation Misho Thrice-Radiant, a Solar, recalls his past life with perfect clarity due to taking both the "past life memory" and "eidetic memory" perks. However, for some reason he cannot recall anything of his current life before exaltation.
