sentient answering machine

I dreamed that I was suddenly in Kentucky. I didn't expect to be there, but I immediately accepted it. It was late at night, and I was walking. I decided to phone my sister and tell her I was in town. I called her, and her answering machine picked up. Her machine's outgoing message seemed aware of the situation and gave me specific details related to it although my sister was asleep or something and wouldn't know I was around until she woke up and checked her messages.
