This dream indicates that the dreamer harbors some feeling of guilt or shame for having taken something that did not belong to him in real life. You should ask yourself if you have looted something, or maybe stolen someone’s partner. The key word is “to pirate”; therefore the dream does not have a positive interpretation. Perhaps some unscrupulous person is taking advantage of you, or you of him. Pirates can be romantic, but they are also violent and dangerous. The dream is interpreted as a warning to work with caution.
