A bear in a dream is a very rich and complicated dream symbol.
They hibernate in a cave and they are generally not predatory animals.
A bear is only aggressive when provoked, and as such times he is dangerous and deadly.
However, this may be a part of a healing cycle, where the dreamer has retreated into himself in order to regenerate and in order to create something new and valuable in his life. Bears are highly regarded symbols in a variety of cultures and traditions, including the Native American tradition.
Carl Jung said that all wild animals represent latent affects (feelings and emotions).
The interpretation of the bear in a dream may be influenced by your perception of it and by the events in the dream.
The bear may represent qualities in your character or specific aspects of your personality.
Bears are usually associated with danger and aggression, but this is a very narrow view of this powerful dream symbol.
