Dead Emperors - Ill Omens Lyrics

I feel the pressure rising, bursting at the seams
The way that things are looking, it's like an awful dream
And I feel the weight upon me

The clouds have gathered closer, there's lighting in the air
Each time I think I'm moving, I just stop and stare
And I feel like something's coming

Is there something on the horizon?
A portent warning me away
A bloody moon is slowly rising

Vultures have grown their numbers, there's a fever in their eyes
It can't be long until they plummet from the skies
And I feel like someone's coming

Is there something on the horizon?
A portent warning me away
A bloody moon is slowly rising
What does it mean?
