Mada, the appearance of your first cousin in your dream, especially given that she passed away a few years ago, is quite significant. This encounter in the dream realm is often representative of unresolved feelings or lingering connections that you may have with her or with the past she represents. The fact that she called you, even though you don't remember what she said, suggests that there is a message or a form of communication that your subconscious is trying to convey. It could be related to emotions or memories that you haven't fully processed or acknowledged.
Dreaming of deceased loved ones is not uncommon, and it often indicates that there are aspects of your relationship with them that need closure or further reflection. Your cousin's call might symbolize a need to reconnect with certain parts of your past that she is associated with, or it could be a call to address something in your present life that echoes those past experiences. This could range from unresolved grief, unfinished business, or even positive memories that you might want to cherish more consciously.
Additionally, the fact that the details of what she said are unclear can be quite telling. This ambiguity might reflect a sense of confusion or lack of clarity in your waking life about how to process these past emotions. It might be worthwhile to think about your cousin and the impact she had on your life, contemplating any unfinished feelings or thoughts you have about her.
