For those who struggle with self-esteem, can lucid dreaming help to improve one's own self-esteem?

Can your subconsious manifest into a dream character? And can you "counsel" your DC?

Are you able to change your thinking and attitude through lucid dreaming?

E.g stuff like telling yourself not to be lazy, to improve self esteem, to end a trait like selfishness, to encourage an emotion like happyness...
