Most think of knowledge as light
But it really thrives at night
When thoughts flow like comet flight

A spark unseen has no meaning
Memory soon after its birth is weaning
The mind is ever cleaning

Only at night can ideas unite
Sometimes in nightmarish fright
They clash to provide insight

An abnormal mixture of bric-a-brac
May upset the normal track
Cause a forgotten flashback

A juxtaposition of random visions
Provides meaningful collisions
Will form constructive revisions

So, submit to the fearful dream
Give in to its varied scheme
You may find life's underlying theme
