My gut feels as though it’s bursting

My gut feels as though it’s bursting
Trying to burst out are thousands of birds
Thousands of squashed birds are inside me
Trying to force their way out
My belly will burst open
The birds will explode into the sky
Bloodstained red birds
Birds dripping in blood
Will swarm into the sky
They will form flocks of birds in the sky
And before they all fly away
It will rain blood
