Ancestor
Ancestors symbolize one’s self with its history. Without the line of ancestors, one is nothing, but in their company, one is “everything.” Ancestors and similar symbols (such as “the dead”) appear in dreams, according to von Franz, at critical times in life—for instance, when one faces life-changing decisions or at a point critical to the individuation process (1995, pp. 317f).
Grandfather, Grandmother
Our parents’ parents in dreams are more strongly associated with the symbol of the wise old man/woman.
The grandfather can represent the “chief,” who, along with his descendants, by virtue of his greater age and therefore greater wisdom, holds much more mana than one’s own father. While our father as a dream symbol tends to possess a distinctly personal quality and represents a related complex, the grandfather has a more impersonal quality and may instead refer to the archetype—the wise old man. The same applies, of course, to figures like the maternal grandmother.
Because these figures are connected to the collective unconscious, they often possess an uncanny quality—the sorcerer tends to be an old man, and the witch an old woman.
