A private written record of daily events and inner life, appearing in dreams as a store of memory, secrets, and self-account.
In dreams the diary usually turns up as a found, lost, hidden, or exposed object. Common scenes include discovering an old diary, being unable to read one's own handwriting, finding pages blank or rewritten, and having someone else read the diary without permission. Sometimes the dreamer is writing in it, and the entries then often describe events that have not happened yet.
The symbol covers several ideas at once: memory and its reliability, privacy and secrecy, and the gap between lived events and the account of them. Which of these applies depends largely on who holds the diary in the dream and whether it is locked, open, or damaged.
Personal diary-keeping has a long literary history. Heian-period Japanese court writers produced a recognised diary genre (*nikki*), and the *Tosa Nikki* of the early tenth century is one example. Samuel Pepys kept his diary in the 1660s. The private diary as a confessional object became familiar in modern Western culture, where the locked journal is associated with adolescence and with intimate disclosure.
Jungian
The diary can stand for the ego's attempt to record and hold its dialogue with the unconscious. Jung's own *Red Book* was a written and illustrated account of his visions and active imagination, kept as a deliberate engagement with unconscious material. In this reading a dream diary is a container for that dialogue. A diary whose pages are illegible or have been changed points to material that has not yet been integrated into conscious understanding. A diary in another person's hand may represent a shadow or other inner figure who holds part of the dreamer's story.

Freudian
The diary is a place for what is kept from others, and a dream of having it read or stolen corresponds to the anxiety of exposure and the work of censorship. In Freud's account the dream distorts its latent content so that wishes the dreamer cannot accept can pass the censor. A diary can appear as the manifest image of that hidden content, or as a source of day residue, the trivial recent experiences the dream draws on. Fear that the diary will be discovered stands in for fear that the repressed wishes it holds will be discovered.

Cultural
Diary-keeping has taken different forms across traditions. The Heian *nikki* were literary works as well as personal records, and Puritan spiritual diaries were written to examine the conscience and track signs of grace. In modern Western folklore of adolescence, the locked diary is a symbol of privacy and of the formation of a self apart from family. A diary in a dream often draws on whichever of these roles the dreamer's culture assigns it: a private confidant, a confessional document, or evidence that can be used against the writer.

Neuroscientific
Dream content is continuous with waking concerns and memories, which Domhoff's continuity hypothesis describes through large collections of dream reports. A diary image fits this pattern, since it concerns autobiographical memory, the subject matter REM sleep is thought to process and consolidate. The diary is also an object of the sleep laboratory, because written dream reports are the standard raw data of dream research. Diaries that appear blank or unreadable are consistent with the instability of text and fine detail in dream imagery, which sleep researchers link to reduced activity in prefrontal regions during REM.

Religious
In Christian scripture, books record human deeds before God. Revelation 20:12 describes books opened at the final judgment, and Augustine's *Confessions* is a written self-account addressed to God. In Islamic tradition, the Qur'an describes noble recording angels (*kiraman katibin*) who write down every act (82:10-12), and a personal book of deeds given to each person on the Day of Judgment (17:13-14). A diary in a dream may therefore be read in these traditions as an image of an account being kept and of eventual answerability for it.
