"Graveyard" as in graveyard shift, the very early morning hours when most people are asleep. Also known as overnights.
Oh, haha! It was too good to be true!
I'm a little weird, but sometimes I like to visit ancient graveyards in my country when I go to the cities, and look at the beautiful art in tombs and graves from 19th century and older, and the walls full of plants and all that.
I also love to visit ancient churchs, and everything in that spirit, you get the point.
