By association with mythology and children?s fables a boar can suggest evil, or rather overbearing aggression. It also suggests abundance and vitality. The boar was once much associated with feasting and festivals and can thus signify lust and gluttony. One of the ways in which the dream mind can bring matters to our attention is by a play on words, and since not many people have contact with the animal per se, for this to appear in a dream usually indicates a 'bore'. Consult the entries for Wild Boar in Animals and also for Pig.
Fierce, independent; volatile and easy to anger; stubborn. Dreaming of this animal can represent:
Having too much of one of these qualities, or that you could benefit by being less this way
Not having enough of one of these qualities, or that you could benefit by being more like this
Someone or something in your real life with whom you associate one of these qualities (an event, situation, threat, etc.)
For more clues, pay attention to what the animal was doing or any particular characteristic that stood out.
