If you get a piece of advice in a dream, the dreamer should seek positioning in himself rather than in the outside world. Perhaps the part of his character that has so far been neglected will further help him.
Taking other people's advice in a dream means that the dreamer realizes the need to do a certain job, even though he feels excluded. Giving advice to others shows that the dreamer has a sense of helping others.
On a spiritual level, the advice in the dream indicates that the dreamer is conscious. The high-level self often expresses itself in making suggestions.
