To dream of killing someone or that you are being murdered may suggest that your unconscious is trying to kill off an unpleasant or unneeded aspect of yourself.
Dreams about knives may suggest that there is something in your life that needs to be cut out; you may need to cut ties or sever a relationship with someone; or a habit or negative behavior needs to be stopped or ‘cut out’.
The clothes we wear in waking life help identify us – they represent how we want others to see us. Clothes also hide our imperfect bodies, and metaphorically, our emotional and psychological imperfections. When we aren’t wearing clothes we are stripped of our identity and others can see us as we really are.
