Analysis of Creepiness of sleep

A sudden heaviness of eye lids,
No control, no strength to move even a brow,
Drunk out of blues, dizziness accompanies,
Never have i visited a sleep brew,
Why do sleep keep bothering me?

Shows up during class sessions,
But disappears during leisure,
Humbled i can be, aiming to gain,
Then boom! Villainy interrupts,
Why do sleep keep bothering me?

Pah! Fights a battle that is unplanned,
An enemy of progress it has become,
Have no fatigue, healthy and rested i am,
But during classes weary and wornout I am,
Why do sleep keep bothering me?

All my school life it is the antagonist,
I being naive, confused protagonist,
Gives a sensation of great boredom,
Before lessons it's no where but during,
Why do sleep keep bothering me?
