An older couple wakes up in the morning. The husband looks over at his wife and says: “Wow! You wouldn’t believe the dream I had”.
The wife replies: “Yes, go on tell me”.
So the husband says: “I had a dream that you left me after 50 years of being married”.
The wife says: “Oh, it sounds more like a nightmare”.
The husband says: “No, I am sure it was a dream”.
