You will not anger unless you are provoked. Look up some videos of a black bear. What do they do? They usually sit around and sleep or walk aimlessly unless they are hungry in which case they fish. If they do go fishing then they can sit in the water for hours and will only get out once they have caught enough fish to satisfy them, or unless they are vehemently provoked. You are the kind of person that is not provoked easily.
No matter how many people try to get on your nerves, you maintain your thick skin in the face of adversity, preferring to focus on your personal endeavors rather than worrying about all of the people fussing over you. Not only that but you have the capability to dedicate yourself to a single task with much fervor and dedication until you see results or until you are taken out of it by someone else, but again this will not happen easily because of how personally entranced in your work you are.
If you see a black bear wandering around or if you dream that you are hunting a black bear, this signifies that you are jealous of that ability in others and want it for yourself. You are on a quest of patience, but ironically, that very quest itself is a measure of supreme impatience and will keep you from ever reaching the true goal that you hope to achieve. This is important to note and should not be taken lightly. If you really feel like you want patience, you should be able to wait for it. This is the mark of a truly patient person.
Dreaming that you are attacked by a black bear means that you have not been very patient or respectful as of late. Bears only attack when provoked and the black bear is known for being especially forgiving in this regard. In other words it takes a lot to make a black bear mad so if you manage to do that then you must have been up to some really annoying things lately. The only way to make sure that the bear backs down is to chill out and relax and let the bear relax and then everything will be fine.
Alternatively that same attacking dream could mean that you have been taking things too far or going where you were unwanted. If another group refuses to initiate you into their fold then it is up to you to heed their warning and not insert yourself where you are not wanted. This is just common sense. Do not be a jerk about it, simply realize when you are not wanted somewhere and go by that rather than forcing other people to bend to your own very inflexible will.
