Tunneling To? Poem by Ima Ryma

Tunneling up like a mole, I
Broke out of that cramped coffin, and
Buried alive, I don't know why.
Hoping I'll better understand
If and when I dig through this dirt,
Six feet of it, for a way out.
Recently shoveled doesn't hurt,
Makes digging easier, no doubt.
But then an awful thought did come.
What if I'm digging the wrong way?
Then all this digging would be dumb.
Could turn out to be a bad day.

I wake up, this tunneling mole,
Through my pillow I've chewed a hole.
