Hello, dreams are people's subconscious activities, and our subconscious will record our activities, including all our experiences, which are unconscious. During sleep, the subconscious will spontaneously search for records and piece them together at will. Coupled with the subconscious imagination, it becomes a dream. Therefore, your dream is probably a patchwork of movies, TV series, novels and so on you have seen before. People dream when they sleep every day, but we remember some dreams and some don't. People who think they have never dreamed are not really dreaming, but forgetting.
Dreams you have, especially always dreaming of the same scene, are very meaningful in psychoanalytic dream interpretation, which can be explained from the perspective of psychoanalysis, but the following conditions should be provided: 1 Personal growth experience; 2. A detailed description of the dream; 3. Free association when talking about dreams; 4. Current real life status, etc. Your account is vague, so you can only explain it vaguely:
1. Dreaming of a little pet kitten represents tenderness; Dogs represent loyalty and friends. Dreaming of owning cats and dogs is a symbol of emotion. Maybe your subconscious is yearning for or commemorating some kind of emotion?
The death of cats and dogs probably represents some kind of inner experience of yours. Have you had any emotional entanglements or lost anything precious recently?
Cats and dogs died because they didn't take good care of them. It depends on who takes care of them. If it were you, you would feel remorse, regret, regret. If it was someone else, you might be angry. Experience that emotion with your heart and see if anything similar to your emotion has happened recently. Maybe you have been suppressing an emotion and letting it appear in your dreams.
The above explanation just gives you some reference and inspiration. I am my best dream interpreter. Only in a detailed dream can I have a practical explanation.
If you often have nightmares, are you unhappy or stressed? Or is there something wrong with your body? If it is a physical problem, I suggest you do a comprehensive physical examination; If there is pressure, we must find ways to relieve it. If it is because of emotional reasons, you may wish to talk to trusted relatives and friends to release pressure and emotions.
Treat nightmares with a normal mind, because everyone will have nightmares, people will not have nightmares, and people can't live without nightmares, because, in a sense, it is a wake-up call to our physical and mental health.
good luck
I hope you can adopt it.
