What happens when I can't sleep

Occasionally, when I can't sleep, I write. This might turn into a song:

In the city,
I walk,
There is both light and shadow.
The buildings,
Are tall,
Casting all these shadows.
And I rest,
In the shade in the day,
Where there are shadows.
Like the other lonely, needy, souls,
Who find rest where there are shadows.

I dunno. Interesting idea, yes? I might have it in me to write another verse for this one.

I am now going to drink some decaf tea and try to get at least four hours of sleep. I feel depressed and tired just writing that. With minimal sleep tonight, here's hoping for a good night's sleep tomorrow!
