It sounds like you're experiencing a fascinating mix of emotions and sensations related to your new environment. The feelings of déjà vu can often indicate that you're tapping into your subconscious mind and processing your past experiences, particularly in a new setting.

The fact that you’re having flashbacks to dreams where something negative occurs might be your mind's way of cautioning you or expressing anxiety about this new chapter in your life. It could also reflect your concerns about the changes and adjustments that come with moving, even if the transition has been largely positive.

Since you have a history of dreams that seem to predict your future, it's possible that your subconscious is attempting to guide you or prepare you for potential challenges. However, as you've noted, the bad outcomes from your dreams have not come to fruition in the past, which may suggest that your mind is merely processing fears rather than indicating actual future events.

To navigate this, consider keeping a dream journal where you can write down your dreams and any feelings of déjà vu you experience. This practice can help you identify patterns and themes in your dreams, and may provide clarity or reassurance over time. Additionally, focusing on positive affirmations and visualizing a happy, safe future in your new home can help shift your mindset as you settle in.

Trust in the positive aspects of your new life, and remember that while dreams can reflect our anxieties, they do not dictate our reality.
