The dream of being mauled by bear means you’re being attacked. Either at work or on the domestic front. Someone is harming you.
Bears attack humans when they invade territorial rights. Have you gone over your boundaries or infringed upon the boundaries of another person who may be represented by the bear in this dream?
Sometimes, the bear wants to protect its young cub, which may be nearby. The cause of its aggressive behavior is to protect its young and its territory.
