Trapped inside

The black and white
Is clear to see
It's shades of grey
Are puzzling me
Shades of feeling like
My body's buried deep,
Half asleep, half asleep.

It's a very deep hole,
With very steep sides,
I can't climb out
I'm trapped inside
It's a very deep hole,
With very steep sides
I can't climb out
Lord knows I've tried,
But I'm trapped inside
You know I've tried,
But I'm trapped inside.

What is it with me,
I make no sense
Why is it
I talk in future tense.
When I'm s'posed to sing
My voice it goes to shout
