Hanging from a rope

Not quite the right image, but all I can remember is: I was flying in a car with other people. I had a baby and he had to fly at the end of a rope. I had to latch him on and then latch myself on so we would be hanging apart from each other. I let him go and he was safe. We were flying through a City. There was a dog in part of the dream and a really angry (there we go back to angry again - hmmm) man who was wanting us to come down. I remember we were on an important mission and we were definitely not in harm's way.
