Seeing a girl in your dream represents the innocent, sensitive, childlike, and playful side of yourself. It also represents your feminine qualities or that you have acted prematurely or immaturely on a certain decision.
Dreaming of a small girl shows your pushover attitude.
Dreaming of a girl you have only recently met suggests that you are concerned about what impression you made on her and what she thinks of you. If this same girl explicitly tells you that she doesn’t like you in the dream, then it may be your brain’s way of telling you not to build on your relationship with her.
A man who dreams of himself as a girl suggests that he wishes to act professionally and portray only female parts.
