What does it mean to dream about suicide at night?

There must be a tacit understanding before dreaming of suicide, which often represents your potential defects and makes you fast. I really want to drive fast, and I am desperate to understand one thing, which will bring bad influence at the same time. So this dream is to remind you of reality, pay attention to perfecting yourself in reality, and have shortcomings, such as always being grumpy and so on.
