I'm not sure if it was a nightmare, but last week I awoke a 5:00am to the distinct sound of an old type writer typing away. I listened to it for over a minute before I decided to get up and investigate.
When I lifted my head from the pillow... It stopped.
We don't own a typewriter and everyone was asleep, I still have no idea what made that noise.
