Your dream contains several elements that can be interpreted in various ways, particularly in the context of personal feelings, cultural significance, and life situations.

1. Setting in a Hindu Temple: Temples often symbolize a place of spirituality, introspection, and a connection to the divine. Being in a temple may indicate a search for meaning or a desire for spiritual growth in your life.
2. Menstruation: Dreams about menstruation can relate to themes of femininity, renewal, and the natural cycles of life. The fact that you are on your period in a public setting may suggest feelings of vulnerability or a desire to express a part of your identity that you typically keep private.
3. Concern about the pad leaking: This may reflect worries about being exposed or vulnerable in front of others. The act of removing the pad in public could symbolize a release of something you’ve been holding back or a need to confront a personal issue.
4. Family presence: The presence of family, particularly your aunty who represents traditional values, may indicate a tension between your personal beliefs and the expectations of your cultural background. It suggests a need to navigate your identity within your familial and cultural context.
5. The blue bag and laptop: The blue bag could represent your personal space or emotional state, while the laptop might symbolize your thoughts, ideas, or work. The fear that the blood might damage the laptop could reflect concerns about how personal issues might affect your responsibilities or aspirations.
6. Finding a spare pad: This indicates resourcefulness and a proactive approach to addressing your needs. It suggests that you are capable of taking care of yourself and finding solutions, even in uncomfortable situations.

Overall, your dream seems to explore themes of vulnerability, cultural identity, and the balance between personal needs and societal expectations. It could signify a journey of self-acceptance and empowerment, as well as a desire to reconcile traditional values with your own beliefs. Reflect on any current situations in your life that might relate to these themes, as your subconscious may be prompting you to address them.
