My Art, My Memory

A Character has Amnesia of some sort but is also good at drawing. Unknowingly they start incorporating things from their past into their works of art.

Anime

 * In Tenchi Forever, Tenchi is being held in an alternate reality with an altered memory so that he doesn't remember any of other main characters. However, he unknowingly paints Ryoko twice.

Film

 * Tangled has a pretty good example of this, but major spoilers:
 * Fifty First Dates has the female lead unable to create any new memories, each time she falls asleep she'll forget everything that's happened during the day. However after Adam Sandler has gone off convinced there is no future for them, we find out that she's been drawing his face, over and over again.
 * Dead Again - The recurring theme of scissors in Grace's art is a clue to a murder that happened before she was born.
 * Related: In Waterworld Enola, a girl with a fabled map to dry land tattooed on her back, draws exotic things like trees and horses...which of course nobody has seen in a few hundred years.
 * In Regarding Henry, the main character who suffers from amnesia after being shot on the head, keeps drawing pictures... of a Ritz crackers box. This eventually leads him to.

Live Action Television

 * In the second season of United States of Tara Tara, who has DID and can't remember large chunks of her childhood, crafts a model of a house. Later on in the season she and her sister visit the foster house they went to when they were really young. Guess what the house looks exactly like.
 * Kyle XY: in one early episode Kyle had amnesia but started drawing symbols he remembered in the form of pointilism.
 * The TV Movie Twitches had the two main characters write and draw things about their infancy in their native demension.
 * One of the episodes of John Doe had a "psychic" drawing pictures that lead the police to rape/murder victims. Turns out she was a survivor, and was just remembering her own attack.
 * The protagonist later in the last episodes.
 * Another variation: On one Supernatural episode Amy Acker guest starred and her traumatized son barely speaks about the Monster of the Week he's seen, but draws clues to it.

Literature

 * A musical variation in Robert Heinlein's short story "They". A man believed to be insane can play beautiful music on the violin. Later on he dreams about his past life in a higher level of being, including hearing music swelling out of every living thing - presumably the source of his musical ability.
