Dreams involving ex-partners and significant others can often reflect unresolved feelings, desires, or conflicts within your current relationship. The apocalyptic setting may symbolize feelings of chaos or transformation in your life.

Seeing your exes could indicate nostalgia or unresolved issues from those past relationships that still linger in your subconscious. The act of being intimate with your exes in the dream suggests a longing for certain feelings or experiences from the past that you may miss, or it could signify a desire for freedom and exploration outside of your current commitment.

Your fiancé searching for you may represent a sense of obligation or commitment you feel in your waking life. The conflict between wanting to be with your ex and the reality of your current relationship could reflect internal struggles about loyalty, love, and the past.

Consider reflecting on the following:

1. Are there aspects of your past relationships that you miss or wish to explore?
2. How do you feel about your current relationship? Are there areas that need attention or communication?
3. What does the notion of an apocalypse signify for you? Is there a sense of change or fear of loss in your life?

This dream may be prompting you to address these feelings more openly, both with yourself and with your fiancé. Communication is key in navigating complex emotions.
