[ WP ] Write a story that starts like a Christmas tale but slowly becomes a Cosmic Horror story .

T'was the Night before Christmas, and all through the house, 
 
 Not a creature was stirring, not even a mouse. 
 
 Young Jimmy was sleeping, so quiet in bed, 
 
 With dreams of the morning and presents in head. 
 
 What Santa would bring him, such mystery joy, 
 
 The perfect day coming for this little boy. 
 
 When somewhere out someways in ocean's abyss, 
 
 The groud began stirring, the water to hiss. 
 
 Jimmy's young mind did start to unravel, 
 
 With darkness, and shadows, and stygian travel, 
 
 Through plains of pure torment and fields of no hope, 
 
 Presents forgotten, young Jimmy awoke. 
 
 Enveloped by twilight, voice like a dragon, 
 
 `` Cthulhu r'lyeh wgah'nagl fhtagn.''
