Arms are significant as a symbol of surrender, wisdom or action. One arm upraised denotes commitment but sometimes also suggests vengeance. Two arms raised sideways signify supplication; raised forwards suggest welcome. Arms - in the sense of weapons - are used to protect and defend. In olden times there were quite a series of rituals and stages of initiation with the Page becoming the Knight and making the transition from the arms bearer to the user of weapons. Dreams can mirror these initiatory rituals. It is worth noting the significance of the placing of the arms. If they are placed across the chest we are defending ourselves. If we are held in or by someone elses arms it suggests a need for security. A coat of arms or other such insignia suggests a form of recognition. Also consult the entries for Body, Sword and Weapons.
