It stabs into your brain, and all you can see is sparks.
Over and over, like it's probing for something, like you could have hidden something in there one purpose just to spite it, but it's still poking around so you don't know what the fuck.
I mean, you broke your head open last night, and something fell out and splat on the ground, so wasn't that it? It keeps stabbing, trying to find whatever you might have hidden from it. Because apparently you're trying to hide something from an inanimate probe.
Before you know it, you're hundreds of miles away, and the train tracks and siamese boxcars and appendages are nowhere in sight. The heat of the ground long dissipated, though once you lived in the sky you now call underground your home. Too bad the bugs got there first because now they won't leave you alone, not even long enough to make a sandwich. You try to get rid of them but they leave a bright purple stain in the wall so you never forget that they were there first.
An avalanche could start at any moment because you won't bother to clear the rocks. You waited too long and now one has gone through your head. Guess how it found its way in?
All the while you emerge from underground occasionally but don't bother trying to fight its gravitational field. Too bad it will inevitably seal you in when the ground turns to ice and all you can see are tiny little points that stick together one on top of the other until all you can see are the insides of your own eyeballs. Try living with that.
And it continues to drill.
