1, you have a heavy psychological dependence on this dog. It's a need for your psychological security. Another way is to guard.
2, your psychological endurance is not good, it is difficult to establish a certain sense of security.
You have deep feelings for this dog, and you always feel that you should do something for it, but you can't do anything. In your dream, your dog left teeth marks on your arm, but it didn't bite you. In your dream, you can explain your guilt like this. It gives you security, but you don't ask for anything.
If you wake up and see the tooth marks on your arm, there is only one possibility, which is called hypnosis or psychological suggestion. Strong psychological suggestion will affect the body. Therefore, don't associate this phenomenon with the theory of ghosts and gods.
What you feel in your dream or reality is mostly a psychological phenomenon and a manifestation of personality traits. In this world, there is death when you are alive, parting when you are together, and sadness when you are happy. This is an emotional experience that we must experience.
It is because of these emotional experiences that our life has become rich and colorful, and we have become strong and rational day by day. Bless this partner who is with you in your heart. Who can say that its departure here is not the beginning of the other side?
Finally, have a good dream.
