A child lies in bed the night before Christmas, dreaming about candieshttp://www.gutenberg.org/files/17135/17135-h/17135-h.htm

1- Twas the night before Christmas, when all through the house
2- Not a creature was stirring , not even a mouse;
3- The stockings were hung by the chimney with care
4- In hopes that St. Nicholas  soon would be there;


5- The children were nestled all snug in their beds,
6- While visions of sugar-plums danced in their heads;
7- And mamma in her kerchief , and I in my cap,
8- Had just settled our brains for a long winter's nap,
