I am familiar with the death bell from my childhood. Without understanding it, I usually sensed a strange atmosphere. My parents knew most of the people in the village and often knew, or at least had a guess, who the bell was ringing for. Sometimes it seemed like a form of relief, other times the opposite.

I also find this behaviour in your place very strange. Why would anyone ring the death bell for someone several times a day? Nobody dies twice.

I don't know if this is done to stress people out. My thought is rather that if it's done too much, people will start to ignore it. Fake news, so to speak. The actual meaning is lost. Maybe that's why...?
