Why do some people sleep with the light on,
And others with it off?

Does it help us sleep?
Or is it simply the comfort
Of the things we know?
The things we see?
The things we love?

You say,
"I cannot sleep,”
Yet if you actually tried,
I’m sure you could.
Is it a lack of willingness
That stops us from sleeping?
From dreaming?
Or is it something more?

Is it subconscious,
Or is it an entirely conscious act?
Some things we never shall know,
Oh well,
I suppose it’s another one of life’s mysteries.
