Dreams in which this symbol appears tell us that it is inadvisable simply to reject the acquired knowledge of generations as out-of-date and old-fashioned.  The image of an old man can also be symbolic expression of inflexibility and incompatibility.

Olives

Gathering olives with friends foretells favorable results in business and delightful surprises.

Onions

Seeing quantities of onions in your dreams, represents the amount of spite and envy that you will meet, by being successful.

Oranges

Seeing a number of fruit bearing orange trees is a sign of health and prosperous surroundings.

Owl

To hear the voice of an owl in a dream warns the dreamer that death creeps closely in the wake of health and joy. Bad tidings of the absent surely follow the dream.
