Analysis of Buried Deep Down

I was buried deep down in my bedclothes
When my mother reassured me and said,
"Hush-a-bye, close your eyes, go to sleep now
For no monsters live under your bed.

No ghouls lie poised in the closet
To jump out and give you a start,
The cupboards are empty of goblins
That would feed on your flesh in the dark.

The tippity tap on the window
Of fingers that fill you with dread,
Is simply the patter of raindrops
And not as you fear the undead.

The ghostly white glare through the skylight
Is only a moon so benign,
So hush-a-bye baby to sleep now,
And remember you are thirty-nine!"
