Autograph dream of getting someone’s autograph represents “betterness” that can’t be denied. It may also represent a memory you have of a positive situation that proves your better than others in some way once and for all.
Alternatively, an autograph may reflect approval from an original or authoritative source. A person or situation that lends extra credibility to your claims or achievements.
To dream giving someone your autograph represents giving your consent or approval to someone. It may also reflect using your expertise, experience, or status to improve someone else’s reputation.
