Your dream seems to hold significant personal and cultural symbolism, particularly around themes of vulnerability, self-acceptance, and the balance between tradition and modernity.

1. Setting in a Hindu Temple: Temples often represent a place of spirituality, reflection, and community. Being in a temple during a significant family holiday like Thanksgiving may indicate a desire for connection with your roots or a search for spiritual grounding.
2. Menstruation: This symbolizes femininity, renewal, and the natural cycles of life. In many cultures, menstruation can also be associated with feelings of shame or embarrassment, but your comfort in the temple suggests a personal acceptance of your body and its functions.
3. Public Setting and Family Presence: Your family being present may indicate feelings of vulnerability in front of loved ones. It could reflect a fear of judgment or concern about how you are perceived, but the fact that you feel no one can see you suggests a journey toward self-acceptance.
4. The Sanitary Pad and Pouches: The leaking pad and your urgency to manage it may symbolize a fear of losing control or being exposed. The beige cloth pouch and the blue bag with your laptop indicate your desire to protect important aspects of your life (like your knowledge and work) while navigating personal challenges.
5. Finding a Spare Pad: This part of the dream can represent resourcefulness and the ability to take care of yourself amidst discomfort. It suggests resilience and the importance of being prepared for unexpected situations.

Overall, this dream may reflect your feelings about accepting your identity and personal challenges while navigating social and cultural expectations. It encourages embracing your femininity and the natural processes of life without shame. Consider how these themes relate to your waking life, as they may provide valuable insights into your current emotional state or personal growth journey.
