Your dreams, fights and killings are all common. There are all kinds of possibilities: discomfort around you, not relaxing or being affected before going to bed, or recent mood (as you said, worrying about social security) may cause dreams.
As for your husband's dream a few years ago, there are two possibilities: first, your husband has a strong sixth sense, and some people will feel what happened and fall asleep; Another possibility is that your husband was a little aware of his feelings before, which may be a look and an attitude of the other party. Although he didn't know what it was, he felt his feelings changed and then fell asleep. That's the truth.
So don't worry about this day. In addition, talk about the predictive role of dreams. Some people have prophetic dreams, but such people are rare. And prophetic dreams are often not so direct. Your husband's dream yesterday reflected his mood and reality. Don't think too much, hehe.
Besides, the dreamer is in Korea. I saw in Korean dramas that Koreans believe in dream interpretation and have a lot of research. What do you know? Can you find some theories or books about Korean dream interpretation? If so, you can introduce it. Hehe, thanks in advance.
