I have my own plans. What do you mean?

Under the circumstances that people can't perceive or control, some things seem to have been predestined or arranged. "I have my own arrangements" is a common saying, which means that something seems to have been predestined or arranged without people's awareness or control. Among them, "in the dark" refers to a force or destiny beyond human understanding and control, while "self-arrangement" refers to that these things have been arranged by this force or destiny, and no matter how hard people try or resist, they can't change it.
