Unbidden in the night
an idea sparks to life,
waking me from restful sleep,
with the impact.

The act of contemplation
sets the thought in motion,
slowly moving at first,
but gaining inertia fast.

Soon it is moving
close to the speed of light,
ricocheting around my skull
like a BB shot into a coke can.

Bouncing round and round,
and keeping me up for hours,
until finally, energy is spent,
and it winks out of existence.

Either because I have gotten up
and written it down, because it's good,
or it simply died of its own volition,
and I go back to sleep, as the alarm rings.
