I know of this. My son suffered a bout of this years back with the sound of chewing, sniffing, loud breathing throat clearing. Basically any people head noises. He had to run, get away, make it stop. The noises triggered fits of rage and crying. He also had this with seeing certain things, like an obese person. It seems related to OCD in that some inocuous stimulus triggers anxiety, panic, and the compulsion to get away and cleanse from the offensive experience. Intensive cognative behavior therapy and a period on medication helped him settle his symptoms. You are not alone.
