Dreams are sort of messages from our soul .If a dream is reoccurring ,that means message is that important so it is worth reliving it again .They probably will not stop till you do not debunk its meaning and take the right actions .
Wolves are pack animals ,they rarely are wondering on their one .
Think of your relations with your family and people around you .
Do you go well with them or you are lonely wolf sort off ?
Did someone betrayed your trust and loyalty ?
Do you have problems with physical and emotional bullies or you are one ?If there is emotional issue of this sort your anger and your sense for survival surfaces in the shape of Wolf .It appears as if you are trapped in constant circle of fear anger which is present in situation what has to do with .You probably supress this anger and fear ,but they are finding your way to make themselves known .You fear the Wolf that comes to hunt you (the emotional or physical bully) ,but in same time you want to make this person feel same way and that is why you became wolf .
So it becomes closed circle of fear ,anger and rage .You probably try to supress this anger deep down in the murky waters of subconscious ,but it is there and it is hunting you .
Also Wolves are smart they tend to work in groups and chase the prey till full exhaustion not given it any way to escape ,and it same time they make themselves known very clearly so they can spook the prey .Does that feeling seems familiar to you either being the prey or the wolf ?It is interesting that you play both roles ,I think in the one you are the prey you are the victim and in same time you supress your anger and vengeance ,because your morals stop you .But soon or late this predator in you will get to free if you do not deal with this issue we can not take fear ,horror and pain forever before you explode and snap out .
I had similar dreams but what was chasing me was my shadow .I never could escape from it but it could not catch me either .I refused to accept my dark side ,because my morals and the dreams kept repeating .And sometimes after so much chasing ,pain and fear I would become a monster without a shadow seeking vengeance .Dreams kept reoccurring till I did not realized my own anger issues and my fear to be myself to not be rejected and abandoned .Once I resolved this issues the dreams stopped .You may want to start working with shadow magick(the Shadow Self ) or seek councelling help .
