Confused

Did my walk end early?
Where am I?
Scratching my arm absentmindedly
I turned to see where I had been
And saw only a cracked walkway.

Scratch scratch scratch and...
That incessant buzzing!
Why won't the insects leave me alone?
Swatting at air I start walking
And stumble.

I was going somewhere
But I cannot remember where.
Clenching my jaw I glance about
With a sense of dread on a sunny day,
And I scratch.

I remember when I was young
And thought death was an eternity away...
The air is thick,
My arm is rubber,
And I am lost.
