Song Ideas

Yesterday I described the backwards process through which I am writing my latest song. Though I have composed an entire song form (melody, harmony, chord structure, and instrumentation), I am lacking lyrics. Only two lines are filled in thus far:

Clock reads three; I can barely breathe.
Words a knife; pierce me in my sleep.

How may a song flow from this concept? Is this a tale autobiographically describing any instance of sleepless, stressful nights? Do these words describe my struggle with fear? With failure? With feelings of inadequacy?

Maybe these lines are not about me at all. Perhaps they are about a buddy of mine who wonders if anyone likes him. If anyone wants to be his friend. Or is it about a youth in the Communicycle program whose dad has departed the house leaving a mother to care for three children?

What if the lines begin to describe the horror of betrayal on Maundy Thursday leading to the death of Friday?

I am slowly realizing the value of a generic lyric - one that can be bent and flexed to mean any number of things in the mind of the listener. As details fill the gaps of a story, the number of listeners able to internalize it will undoubtedly decrease.
