If you dream of flattering someone, it may indicate significant changes in your life. This suggests that you might be shifting your perspective towards others or seeking to improve your relationships with them. Sometimes, giving compliments can mean trying to please someone for your own benefit. Such a dream warns you that if you wish to be accepted by others, you must maintain your honesty.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Flattery" (page 169).
Ingratiating oneselfto someone for worldly profits, or to gain access to knowledge, or to find ajob to help him better apply his religious obligations in a dream means honor, correcting one's religious practices or attaining one's spiritual goals. It also means evil consequences if one does not usually strive after such needs, or if he presents his needs too favorably, or ifhe does so in a dream soliciting favors from a woman he knows. It also means escaping from the dangers of his enemy. However, flaterry and ingratiating oneself to others in a dream also could mean giving preference to others' needs over one's own, trueness and being charitable. (Also see Adulation)
