Bell sound in the Darkness

Imagine you open your eyes and wake up in complete darkness. Perfect blackness. You realize you can't move and you can't talk. You have no sense of body and don't know if you're lying or standing where you are. All you can do is hear. You hear mysterious voices. Sometimes far, sometimes near... Horst is in exactly such a position. He doesn't realize until very late, too late what's wrong with him. This realization almost robs his mind. It doesn't help him to get his memory back. On the contrary. Now he knows why he's in this situation.
