Analysis of Midnight lullaby

I sang this to myself
  In the middle of a far-reaching night
    My head dipped in warmth and heart in
        pain
"Oh dearie, time had come and gone by,
   Laughs you laughed all day and tears,
       Gone dry.
So, why are you waiting?
       And, what is it for? "
         I sang this to myself, and,
Sang it for long,
      Only to realize that I was wrong.
          The one I was singing to wasn't really
             me,
For I trapped my heart,
     Trapped it myself, in a faraway sea,
        A sea so deep, I couldn't find its origin
It hid its heart from, just as it did with me
   And I wondered and wondered all night
     Finding a way to reach there.
         I found it, felt it with all my conscious
But the dream snapped quickly
   And back to the nightmare of this world,
     So, I sang this to myself and I sang a
         deeply,Deeply loving lullaby to
             myself.
