I had a dream my cousin who is my enemy died. I was happy
Dreams can reflect our subconscious thoughts and emotions, and they often do not directly indicate how we feel in real life. Dreaming about someone's death, even if they are considered an enemy in real life, does not necessarily mean that you actually wish harm or death upon that person.
In this dream, your cousin could symbolize a part of yourself or an aspect of your own personality that you are at odds with. The dream may represent a desire for resolution or closure with this inner conflict. Feeling happy in the dream could suggest a sense of relief or release from this internal struggle.
It may also be helpful to reflect on your relationship with your cousin in real life and explore any underlying issues or feelings that may be at play. Remember, dreams are complex and can have multiple layers of interpretation.
