To dream of elderly people represents experience or the wisdom to know better. Having "been there and done that." Re-experiencing a similar situation. Sound advice coming from experience. It may also reflect boredom with something you know too well.
Old women may reflect experience with supporting others or being screwed over. Old men may reflect experience asserting yourself or embarrassing others.
Alternatively, an elderly person may represent you feelings of being old.
