You know how dangerous this is

But you can't put the fire out.
It's far too beautiful to let it die anyway.
So it will burn until you start to doubt.
The flames are growing and it's killing you not knowing.
And the flames may flicker
But your heartbeat just gets quicker.
So now it's oxygen or water.
But you're feeding on this feeling
And thriving on the danger.
Oxygen or water?
You'd rather not know which.
