Heya Judge, what makes you say this?
In my own case, because I know my paranoia often wins out over such things...even when it isn't actually happening. Something somewhat akin to compulsive behavior. Where I know I don't need to do something, yet I do it anyways.
So for me, I'm somewhat more prone to think someone is staring at me when they really aren't. That it's just a nebulous, uncomfortable feeling often without merit.
