Dreams involving unfamiliar people and intense emotions can reflect various aspects of our subconscious mind. In your dream, the presence of a mysterious man who acts as a protector suggests a desire for safety and security, especially in light of the threats you experienced. This figure may symbolize qualities you admire or wish you had in your life, such as bravery or decisiveness.

The fact that you felt different in the dream can indicate a longing for change or a new identity, perhaps related to your current relationship or personal circumstances. Your love for this man in the dream, coupled with the absence of your real-life partner, might suggest that you are exploring feelings or desires that are not being fully addressed in your waking life.

Your sister's presence in the dream, despite her passing, could signify a connection to your past and unresolved feelings regarding her. It might represent comfort or the need for familial support during challenging times.

Overall, this dream may be urging you to reflect on your current relationship and consider what aspects of love, safety, and identity are significant to you. It could be a prompt to communicate more openly with your partner about your feelings or to explore parts of yourself that you may not fully embrace.
