To dream that you are being mutilated indicates that there is a waking situation that you need to be careful about. You may be putting yourself in some sort of danger, either physical or mental. If you are mutilating yourself, then it means that you are seeking attention. You are expressing a desperate cry for help. Or you are trying to disconnect yourself from the unbearable pain you are experiencing in an aspect of your life.
To dream that someone or something is mutilated indicates that your integrity is put into question.
