The single headed beast

Months down the line,
if now I may.
Respond to reality, with the head I flay
I ran for it was consuming
It was booming yet grooming.
I was done and left with no space
For this head took up more and more
and not even with the slightest grace.
I plucked it out and now I wait-
for the 10th and final head to grow.
And not realsing until moments ago
I gave into a metaphor I had no intentions to show.
