Every once in a while I dream that I hear the doorbell. Back when I had a dog and two cats when I napped, I'd be sandwiched with them. If I had that dream I would just look at the fur babies. If the dog heard the bell he'd be out there trying to break the door down to greet his new friends. The cats would be off for a hidey hole. If they were all still sleeping on me I knew I was dreaming.
