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'.
