Dream Symbols in The Dream Encyclopedia

by James R. Lewis and Evelyn Dorothy Oliver
An old man in a dream usually represents wisdom, and sometimes forgiveness.

The old man may be either a specific person or a generic aged one who, regardless of his race or color, is usually adorned with white hair and a full beard. An old man can also stand for a deteriorating person whose only power lies in the memory of a journey that has already taken place. Whether the old man exhibits stamina or lacks physical strength also affects the dream’s interpretation.

The Mystic Dream Book

by Stephen Girard
For a woman to dream she is courted by an old man, is a sure prognostic that she will receive a sum of money and be successful in her undertakings. For a maid to dream of it, shows that she will marry a rich young fellow, and have many children by him, who will all become rich.

Islamic Dream Interpretation

by Ibn Seerin
If an old man is seen speaking to him or giving him something, it means he will succeed in whatever he is pursuing.

If the old man is of a pleasant personality and good looks, it means his pursuit is of a favourable nature. Otherwise, it is of an unfavourable nature.
