Dreaming of a swift fox means you applying a high level of trickery to attain what you desire. You manipulate multiple parties like a puppeteer influencing everyone’s actions with a line of string. Your enemies may be on to your tricks, but they are never able to pin down evidence to threaten your work.
The appearance of a swift fox in your dream also suggests that you are a busy person who has to always rush through everything they do. Plus, it indicates that you are being overly annoyed by someone or something, and it may even have to do with an addiction.
