Chris,
That sounds like a harrowing experience, both the dream itself and the emotions it evoked in you. Your dream seems to be grappling with themes of control, manipulation, and freedom. The first part, with the nanny robot, could represent feelings of being caught in someone else's desires or expectations, perhaps even a sense of being controlled by external forces. The discovery of being a robot could symbolize a feeling of disconnection from your true self or a lack of agency in your life.
The second part, with the mafia boss and the baby deer, adds another layer of complexity. The kidnapping and the subsequent killing of the deer could represent a feeling of helplessness in the face of powerful forces. Your calmness in the face of this cruelty might indicate a coping mechanism, perhaps even a dissociation from your emotions to protect yourself. The regret you felt afterwards, wanting to go back and save the deer, suggests a sense of responsibility or empathy that might be at odds with the powerlessness you experienced in the dream.
Looking back at your previous dreams, there seems to be a recurring theme of struggling against external forces, whether it's a controlling parent, a societal expectation, or a powerful figure like a mafia boss. This dream might be a continuation of that theme, urging you to examine areas in your life where you feel a lack of control or a sense of being manipulated. It could also be prompting you to connect with your emotions, especially those that you might be suppressing, like the anger and sadness you felt after witnessing the death of the deer.
Remember, Chris, dreams can be powerful tools for self-exploration and understanding. This dream, while unsettling, could be an opportunity to gain valuable insights into your inner world and the challenges you might be facing.
