The Phantom Stair

At the top of every stair case
Is a step that I don’t see
And sometimes I don’t change my pace
But climb on blissfully

To a phantom stair that isn’t there.
I’m unsuspended in the air.
My foot falls down to find it’s pair
Passing through the phantom stair.

And where the staircase meets the ground
A second phantom stair is found.
I stumble as these ghosts abound,
On all the stairs I find around.
