Sometimes there is a dream that puzzles us, that is, the dead relatives, friends and even strangers are revived in our dreams, and they will feel very scared after waking up. In fact, this is a misunderstanding of our thinking about dreams. The person who came back from the dead in the dream is not really resurrected, nor is it because we miss them very much, but the dream has to let him "appear" in order to express the central idea. Of course, it depends on the concrete analysis of dreams. I can't see the reason for his resurrection in your dream. You can contact him freely and see what he has to do with your dream, and you can find the answer.
3. Your dream is a depressed dream from the psychological point of view, so is there anything that has caused you great pressure recently?
In addition, I am more worried that this dream is caused by your organic disease. You should have a good physical examination.
Your strangest thing is that the cat's tail was cut off. In fact, if Freud's dream interpretation knowledge is used, it is a dream about genital castration. The cat's tail symbolizes the male genitalia in the dream.
