Arriving late for something can mean:
Whatever you are late for in the dream represents something very important to you in real life
You're neglecting a responsibility
You'd like to avoid the thing you're late for, you're dreading it, or you're afraid of failure
You're feeling passive-aggression towards an authority that is represented by whatever you're late for
You feel you
Have too much on your mind or on your schedule, or that you're feeling
Disorganized
Being late and feeling bad about it can mean you are experiencing or fearing a loss of control, or of being controlled by outside circumstances, somehow in your life.A late timeframe, such as late evening, might represent a point late in a real-life process or the timeframe of an actual event in your life.
