To dream that you are stoning someone implies your sense of superiority. You feel you are above other people. Alternatively, stoning someone in your dream symbolises pent up anger and aggression, especially within your personal relationship.
Dreaming that you are being stoned suggests that you are punishing yourself. You feel that you are being judged and are tired of pleasing others. Alternatively, being stoned parallels the insults and negativity directed at you in your waking life.
