Dream Decoding

The dream that i had last week was about my dog. I was in y house and my mom had just came home from work, she opened the front door and like always my dog was there to see who it was. My mom was petting him, my dog left and ran back too my mom but he ran under her legs and ran to go out side, my mom didn't notice when my dog ran out, so i ran after him. But some one had opened the lobby door and my dog ran. He didn't even know were he was going. I was chasing him through out the whole block, I almost caught him on 8th street but he went through the gate and ran to 12th street. i was chasing him and chasing him but he was too fast. I couldn't believe that my dog ran away. I went back home, and to my surprise my dog was there in front of my building as if he was waiting for me. I was laughing!
