default and most high value of user sanity is 100%. some strange things might happen. but at the same time it is normal. strange or weird things make your sanity lose slowly, by 2%. every event user do make weirdness random, if it was normal, then sanity wont lose, or even go up, if not normal then -2%. if sanity is 0-5% - you lose. good luck. (strange here means something paranormal, or just simply scary)
