Demon Floaty Whistling in the Dark

It’s amazing how unterrifying
Spooky mental phenomena can be,
If you know what you’re experiencing,
And you know what others see.

Say you see a shadow in the corner
Of your vision, one that sort of flickers
Like a large, black floaty, but foreigner,
An eye drifter, but quicker.

You know it’s a feature of fresh disease,
A new bug in your visual system,
And you know it’s nothing others can see,
An eyespot not a demon.

You don’t worry about its agency,
About whether or not it’s stalking you.
It’s just your own failing machinery,
Nothing that wants to eat you.
