What does it mean to dream that my little aunt died and became a spectre and killed my cousin?

There are no ghosts in this world. After death, what elements on Mendeyev's periodic table become what, through metabolism, enter other organisms and participate in the new life cycle. I am 64 years old. I don't believe in ghosts and gods all my life, and I have never had the trouble of scaring myself all my life. From a psychological point of view, you didn't mean it when you said "My aunt is very nice". In your subconscious, you still think that the little aunt has a less good side. This subconscious conflict is not normal in dreams. Don't care. This dream is neither evil nor auspicious.
