A older couple wakes up

An older couple wakes up in the morning and 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 20 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.’
