The word scapegoat actually comes from the sacrificing of a goat to appease the gods, and in dreams this symbol can be highly relevant.
If in our dream we are the scapegoat for someone else’s action then we are being turned into a victim. Other people maybe trying to make us pay for their misdcmcanours.
If we are making another person a scapegoat then this indicates a blame shift, and that we are not taking responsibility for our own actions.
Often in families and teams one member takes the brunt of all the projections from the rest of the family or group. He (or she) is continually belittled or laughed at. and can be blamed for all sorts of things which are not their fault. They become the scapegoat. In dreams, however, there is recognition that there is an aspect of cooperation and collaboration in the dreamer. We need to do something to redress the balance, and often the solution can only come from us.
