If you live alone, they'll send a group of goons to come at you at. They don't have to do much to scare you, just bang on your doors and on your windows and at 2-3 in the morning. when you get up to stop them, they run away. You're spooked and think "oh it was probably just burglars." Then you go back to bed. Then the banging happens again at 4am. This time you call the cops, but the cops don't show up on time and don't catch the perps. Now imagine this happening every single day for a week, you're not sleeping, the cops are pissed they have to keep showing up to someone guy ranting claiming people are harassing him and since you aren't sleeping you actually start going crazy. No, you're not permanently crazy, you're just under stress and being totured by not being allowed sleep. This is straight out of the East German Stasi Police handbook on discrediting political dissidents and journalists.
