Dreams often weave together our memories, emotions, and experiences in complex ways. In your dream, the presence of "other mother" suggests a strong maternal figure or a comforting presence in your life, someone who represents support, love, or guidance. The fact that she is not your actual parent but feels familiar could indicate a desire for nurturing or a connection to a different aspect of your upbringing or family dynamics.

The setting shifting from Thailand to your grandparents' house in India may symbolize a return to your roots or a longing for the comfort of childhood and family. This juxtaposition could suggest that you are processing different parts of your identity or heritage.

The black figure you saw could represent fears or anxieties lurking in your subconscious, perhaps tied to change or the unknown aspects of your life. It's interesting that this figure resembled "other mother," which might indicate that your feelings towards this nurturing aspect are complicated—perhaps you feel a mix of comfort and fear.

Your reaction to seeing the figure—falling back and breathing heavily—suggests a strong emotional response to what you perceive as a threat or a significant change. This could be linked to your feelings of growing up and losing your childhood, as indicated by your concern over not holding your stuffed animals anymore. Stuffed animals often symbolize innocence, comfort, and the carefree aspects of childhood, so their absence in your waking life might evoke feelings of loss or nostalgia.

Overall, your dream reflects a blend of comfort, fear, and a longing for the simplicity of childhood. It might be helpful to explore these feelings in your waking life, perhaps by reconnecting with comforting memories or aspects of your childhood that still hold meaning for you.
