Bear
To see a bear in your dream represents independence, strength, death and renewal, and/or resurrection. Bears are symbolic of the cycle of life. You may also be undergoing a period of introspection and thinking. In particular, if you see a bear in your grandmother's house, then it implies that your grandmother is a dominant figure in your life.
The dream may also be a pun on "bare.". Perhaps you need to bare your soul and let everything out into the open. Or there is a situation where you just need to "grin and bear it.".
To dream that you are being pursued or attacked by a bear denotes anger and uncontrolled aggression. You feel trapped. Perhaps you are in a threatening situation—some overwhelming obstacle or domineering and possessive relationship.
To see a polar bear in your dream signifies a reawakening.
