It is about perceived threats that aren’t real, I’ve been doing observational exercises for a few months. Basically walk when you walk into a room, pay attention, where do your eyes go? What’s the first thing you tend to notice? What effect does this have on you if any?
To take it a level deeper try to challenge perception, is this person really a threat, are they even aware of your presence, do they care? It’s work, but if you think about it, humans can be conditioned to think and behave in almost any way imaginable under the right circumstances. It’s a matter of repetition
