Tell me your dream. From your description, your dream is a romantic psychological feeling about what happened before going to bed: first, you buy clothes with your best friend, who may refer to your boyfriend. Going to the dark fitting room shows that the place you are going to is a bit mysterious, insecure or oppressive, which may be your superficial feelings about your boyfriend's home. The little black dog may be the transformation of a cat I saw at my boyfriend's house. A punk is laughing at you. Maybe it means your mother. You find that clothes have become junior high school uniforms. Maybe you think your mother still treats you like a child or a junior high school student. Later, you scolded, ran away, was chased by gangsters, and an old man appeared, probably because of your psychological resistance to your mother's attitude. I guess so. Dreamers can think more and combine with reality (especially psychological activities).
