Dreaming of braces mean learning to listen and preparing for the tough times. Your peers may be arguing with you all the time, do you know why? They are not getting their points across because you are not listening.
You may be shrinking your network as well, and now would be the time to honker down to brace for the worst. Difficult times may or may not occur, but it is best to be prepared and ride it out.
Once you learn to listen and make preparations, then your braces dream has served its purpose in helping you in the waking hours.
