Its a deep type of dark. Pitch black on the edges and darker somewhat spirally and almost almost stroboscopically grows darker as it quickens into the middle. It's a slow type of dark. So slow it seems to be motionless as though movement forms before and after it. It's a quiet type of dark. So quiet it seems to hum in the ear. So quiet it could be termed dark silence? So silent it scares. As though there is a whisper not heard through the ears but felt in the heart.
