Vision of a Hanging Man

Okay, so this one has a bit of a story to go with it.

One night, not too long ago. It was really fucking windy.
I was trying to sleep, but sleep never came.
For the wind kept rattling and howling through my window.
So after an hour of insanity, I took a sleeping pill.
Still, Sleep never came... and the wind howled on.
Eventually, I rose up out of bed and grabbed the nearest thing.
I stuffed a shirt in between the windows in hopes to quell the rattling... And muffle the howling. Eventually, I found sleep.
When the morning came, the silhouette was this.
My shirt, formed the image of a hanging man.
