The Gallery part 2

In the hall of dreams,
Floating in an ocean
Of stagnant water
Eternally birthing
Blood drinking things
Born below the surface
As simpler beings
Who grow and transform
Until ready for flight
Then feed on other galleries
In the middle of the night
They swarm the statues
And paintings on walls
Biting through the heads
Of the relief sculptures in halls
Drinking the hearts
Of the floral gardens outside
Piercing the pleasures
Of patrons and pride
