Knocking back and forth

A whirlwind rocking through the hallway

Air pushed upwards, always upwards

Twisting in the stairwells

Building up speed and noise

A gust on a mission

To blow through the halls

And knock all the doors

To make itself heard

Because it can never be seen

Invisible in the awakened hours

An unseen force of mystery

Only being heard when necessary

Never showing itself

Even when it wants to be
