I wake up earlier than my husband for I leave for work earlier. One time as I came out of the bathroom, I heard the barks of Barbie. Our dogs sleep inside our bedroom. When I opened the door, I heard my husband moaning on the bed, obviously having a nightmare. And there was Barbie barking at my husband. She jumped on the bed and bit the hand of my husband who woke up (the bite was not harmful though). Clearly, Barbie saved my husband from the nightmare.
