An older couple is lying in bed one morning. They had just awakened from a good night's sleep.

He takes her hand and she responds, "Don't touch me." 

"Why not?" he asked. 

She answered, "Because I'm dead." 

The husband asked "What are you talking about? We're both lying here in bed together and talking to one another!"

She said, "No, I'm definitely dead." 

He insisted, "You are not dead. What in the world makes you think you're dead?" 

"Because I woke up this morning and nothing hurts."
