Interruption in sleep

 At midnight I shouted the name Evelyn.  It seemed justified. I shouted loud and clearly and woke my wife. 

I've done this middle of the night shouting before, calling other words. I have never known someone by the name Evelyn or is a character named or mentioned in any of the books I am reading or have recently read named Evelyn. 

My wife had a difficult time falling back to sleep. I never woke up and have a vague memory of shouting.  My wife told me what I shouted.

Later this day my daughter heard the story and reminded me that on the menu the sandwich i ordered for lunch was called Eveylon 13 ... 13 dollars was the price.
