I woke last night in the middle of the night. I've developed a bad habit of just tucking my glasses underneath my pillow insteadof putting them on my bed table, and I accidentally knowcked off my bed. As they fell to the floor, they hit my brass headboard, making a sound like a bell: a low, clear ring.
As this happened, I heard a voice in my head say, the bell tolls for those who will die.
