There is always a bad feeling in my heart these days. I think something bad is going to happen. What happened?

This may be just some kind of psychological effect. You may be a rather uneasy person, right? Compared with that, you are prepared for danger in times of peace, more crisis-conscious, and maybe more introverted. So this situation is actually normal, so you have a bad feeling, which is actually a little superstitious, but you should pay attention recently, or go out less and pay attention. Whether it's traffic safety or other things, should we be more careful? See if we can improve it. Maybe I haven't slept well recently or something. Anyway, you are imagining things.
