I dreamed that there were many cockroaches and ants at home, and I was spraying them with pesticides.

In fact, dreams are still people's feelings and dreams. After all, they are just dreams. Don't care too much about dreams. The more you think about them, maybe it's nothing at all. As a result, you are distracted by thinking too much, which affects your originally peaceful life. Dreams have a lot to do with our experiences and moods during the day. Maybe we are too tired, maybe we are stimulated, maybe what we see during the day will expand at night, so we don't have to pay too much attention.
