Dreams can often reflect our subconscious thoughts, feelings, and experiences. In your dream, the setting of Dillard's and the presence of your mother may symbolize a connection to comfort, familiarity, or even a desire for support during challenging times. The crystal shop, particularly with the emphasis on the tiger's eye necklace, could represent a search for protection, courage, or grounding energy, as tiger's eye is often associated with these qualities.

The interactions with the two girls you grew up with may reveal feelings of judgment or social anxiety in your waking life. The girl who barely spoke to you might symbolize unresolved issues or insecurities you feel about past relationships. It’s also significant that you learned about your mother’s loss of a pregnancy through someone else, which could indicate feelings of being left out of important family matters or a desire for more openness in your relationship with your mom.

Overall, this dream seems to reflect themes of family connection, the impact of past relationships, and the need for communication about sensitive topics. It might be beneficial to have an open conversation with your mother about your feelings and any unspoken issues that could be affecting your relationship. Exploring these themes further may help you process your emotions and strengthen your connections with loved ones.
