Dreams and visions about a bear tell you about clearing thoughts and trying to create space or peace in your life, but especially about an introverted lifestyle. Another explanation is the warmth, family, childhood memories or lack of attention.
Remember that the bear is a project or reflection of your own true feelings, emotions and sadness, so you are the bear yourself.
A bear also stands for a high cuddle level, which you need in your life. Or warmth that you never had in your youth and that you feel you lack. In addition, the bear also tells the different cycles in the life of independence and growth.
The aggressive bear in your dream or vision tells you about the strength you have to overcome your anger, aggression and obstacles. You can also think of perseverance to get where you need to be in life.
A dream or vision haunted by a bear tells of aggression, but also of overwhelming obstacles and competition that you cannot master. You can see yourself facing a threatening situation. You are the one who is being chased, you are aware of your own behavior or influence on the situation.
It may of course be an alternative that you feel that you should not or cannot be who you really are; as it were you are running away from yourself and that beautiful person and energy that flows within you.
