Dream vs. Reality

A few years ago, I was awakened from a lovely slumber by a knock on our front door (our only door). It was my friendly neighbor, Barbara. Apparently, a leak from one of my bathrooms had caused a ceiling collapse in one of hers. She was very kind and we were able to take care of everything and remain friends. Unfortunately, since that morning, I have this problem with "thinking" that I hear a knock on my door. It's always when I'm in that strange state of not being asleep, but not being entirely awake, either. So it happens about once a month--I jump from bed and run to the front door. . .only to discover that my foggy morning mind has played a cruel trick on me. It happened again this morning. I'm looking for a cure.

Hey--did someone on an air mattress Friday night have trouble getting their sleeping bag unzipped or am I really losing it?
