I was in my room and i kicked my dog and she became completely flat
Kicking a dog in a dream can symbolize feelings of aggression and anger. The fact that the dog becomes completely flat could represent your desire to squash or diminish these feelings. It is possible that you feel guilty for being angry with someone or about a situation, and even though you may have expressed it in some way, you feel like you should have kept it hidden. Alternatively, it could represent feelings of powerlessness or a lack of control in a situation, where you feel like you are unable to make any headway or progress. The dream may be urging you to find healthier ways to express your anger and frustration, and seek help if necessary. It is also important to show love and kindness towards animals, and to treat them with care and consideration.
