At some point, we are all guilty of being a little too flattery in our daily conversations. It is a natural way to build rapport and make people feel good about themselves. When we are in a dream and someone is flattering us, it often has to do with how we see ourselves or how others view us. Flattery in dreams can signify many things from insecurity to self-esteem issues.
It could be an ego boost. We need compliments to feel good about ourselves so if you are getting them in your dream, it might be you who is feeling insecure or maybe the opposite. The flattery may fulfill that need for your own validation.
Or it could be a request for attention. Dreaming about flattery could also be that the person complimenting you wants something from you and they may think by giving you a compliment they will get their way more often than not.
