I fell asleep again. It was an odd sensation. The humming I have been hearing in my head, somewhere behind me, increased. Not in volume, but in vibration. Somehow, the frequency increased, like someone was strumming a wire, and had shortened the period between waves of the wire. It was faster, but not speed like how often. It was like pieces of sound were being shoved behind my head over and over. Normally, it fades into the background silence, but now it was so easy to here. I couldn’t help but notice it. It didn’t stay at the same pitch either. It varied and changed. The volume never went anywhere, but I could barely think of anything else.
