Silence
Try this. Turn off the music. Turn off the TV. If you have to, turn off the computer. Then go to another room, and sit. In total silence. Do you hear that? That ringing? People say it is your brain making up a sound to explain the silence. People lied. I cant tell you what is making that sound, but whatever it is, you don’t want to meet it. It is trying to break through. Force its way onto our plane of existence. Now try this. Repeat the first steps. Turn everything off. This time, turn the lights off too. Still hear that ringing? Better hope you do. If you don’t, its because they have finally managed to break through. And no amount of running will save you. — Credited to  TheCoffinDancer.
