Syd, the dream you've shared sounds incredibly frustrating and even hurtful. I understand why this would be upsetting, especially given your current emotional state and sensitivity. It's completely valid to feel embarrassed and exposed when your friend tried to explain your pronouns and your identity was dismissed.
The group setting, reminiscent of high school or church, could symbolize a social environment where you might feel pressure to conform or where your individuality might not be fully understood. The fact that people you knew and didn't know were misgendering you could reflect a broader societal struggle with understanding and respecting non-binary identities, unfortunately.
While it's admirable that you initially tried to be respectful and understanding, it's important to stand up for yourself and your identity when someone disrespects your pronouns. Your friend's support was likely a source of comfort, even if the interaction with the lady didn't go as hoped.
The lady's dismissive attitude, despite being couched in politeness, can represent the challenges faced by non-binary individuals in gaining recognition and acceptance. It can be exhausting to constantly explain and advocate for yourself, and it's understandable that the dream left you feeling drained and emotionally raw.
It's important to remember that your identity is valid and deserves respect. You have the right to live authentically and to be addressed correctly.
If this dream has left you feeling particularly distressed, consider seeking additional support, perhaps through online communities or therapy. There are resources available to help you cope with the challenges of being non-binary in a society that often struggles to understand. Remember, you're not alone in this, and there are people who want to support you on your journey.
