off the ledge

I'm practicing for the end of the world
So I took my seatbelt off to go
Through the windshield.
I hope this will cleanse me before the end.
To shed blood, tears, and vomit
And thus be annealed.
While I lay there on an empty road,
I pray that aliens take me.
They'd take me away in their cold ship
To probe and dissect
and extract what I feel.
