Duke Zhou dreamed that the cut hair fell to the ground.

Dreaming that your hair has been cut off means that you have to clean up your troubles, which is a good sign, because your hair is troubled and won't curl well.

Dreaming that you cut your hair means that you have to quarrel with your close friends or relatives, and the responsibility lies with you. If you dream that the other person cut your hair, then the reason for the quarrel lies with the other person.
