Dreaming about guns and interpreting these dreams depends greatly on your attitude about guns. There are many people who are comfortable with the life-and-death power of guns and use them recreationally. Whether the dreamer is a recreational target-shooter or hunter, guns may not have much significance apart from what is being shot at or who is hunting with you.
However, for others who are more awed by the gun's power to cause death, the gun is a taboo symbol. Dreaming about guns from this context reveals a sense of being deeply threatened by the environment of the dream or persons in the dream. The gun may represent a nearly desperate need to reassert personal control in the situation or to find personal power in relationship to others.
