Thank you for sharing your dream. It contains many vivid symbols and scenarios that could reflect your emotions and experiences, especially following the loss of your partner.

1. Piercing and Blood: The act of getting a piercing, especially with the pain and blood involved, may symbolize a personal transformation or the pain of emotional wounds. The reference to it going through the clitoris could suggest feelings about intimacy, vulnerability, or a sense of loss of control over your body and emotions.
2. Time Awareness: Being conscious of time and the martial arts lesson could indicate a desire for structure or routine in your life, especially after a significant loss. Martial arts often represent discipline and self-defense, which might reflect your need to protect yourself emotionally.
3. Restoration of the Dollhouse and Corner Shop: The restoration themes in your dream, like the dollhouse and the corner shop from your childhood, may symbolize nostalgia and a longing to return to a simpler time. They could also represent healing and rebuilding after a loss.
4. Caring for Children and the Slap: Your interaction with the children, particularly the moment of frustration, might be an expression of your emotional state. It indicates a struggle with feelings of helplessness or anger, possibly mirroring your own grief and the challenges of managing your emotions.
5. The Heart in a Jar: The tiny, beating heart could symbolize love, vulnerability, or the essence of life itself. Buying it from someone who has just been released from prison may represent a desire to reclaim parts of yourself that feel lost or imprisoned by grief. The heart still beating suggests that love and connection persist, even amid loss.

Overall, this dream seems to reflect your journey through grief, healing, and the complexities of emotions tied to love and loss. It might be beneficial to take time for self-care, explore these feelings, and perhaps consider talking to someone who can help you navigate the grief process.
