I suffer from severe obsessive-compulsive disorder and have an almost obsessive obsession with the number 99. Even a bottle of ordinary water must be drunk slowly at the pace of 99 sips. Once, the school bully arbitrarily snatched half a bottle of water from me. I subconsciously protected my "order", but my mistake caused him to injure his muscles and bones and recuperate for half a month. Later, I accidentally entered a horror game. The other players were so frightened that they screamed. But I was extremely calm and counted the weird things around me. I was still confused. Why were there only 98? Where did the other one go?
