Before I open my eyes, I regret even becoming conscious again. Through the darkness, my head throbs with a dull pain, like the inside of my skull is under pressure. This isn't a particularly foreign experience. More often than not, it means I've once again been an unwitting participant in some sort of new experiment. I have yet to figure out if it's something they put in the slop they serve me for food or if they're pumping gas in my room to knock me out ahead of time – and it frustrates me that this remains a mystery.
