Analysis of Sea Serpent

I saw it on a stormy night
When lightning struck the sea,
The waves crushed on the sand with might
the wind howled endlessly.

I stood upon the midnight shore
The rain cold on my face,
The echo of the oceans roar
A haunting sound embrace.

Then with the lightning flash I saw
A creature through the mist,
It’s slender neck rose with the roar
Of lightning, and it hissed.

Its oval head with glowing eyes
A moment caught in light,
A creature found in myths and lies
I saw within that night.

Then with that moment it was gone
Yet in my memory,
I see it in the lightning’s sun
A serpent in the sea.
