Weapons and Sex
Freud thought that almost every weapon was a phallic symbol, and many dream analysts believe that dreams about weapons have sexual meanings.
According to their interpretations, a knife, which stabs and penetrates, can be a symbol of aggressive male sexuality. A gun also symbolizes male sexual aggression, with the firing of a bullet representing orgasm.
If a man dreams of attacking a woman with a weapon, it can be a sign that he has an ambivalent attitude toward women. A woman who dreams of being attacked may be afraid of men or feel sexually insecure. If a weapon malfunctions or doesn’t work, the dreamer may feel anxious about his or her sexual performance.
