Yes, Greentea, that's the kind of thing that can easily happen to me. If I start to feel my audience doesn't believe what I'm saying, it's as if my reality becomes what they're thinking, and I start to believe them
......I've sometimes wondered if I may have an overblown sense of guilt that's deeply unconscious - it feels like deepdown I'm primed and ready to judge myself and to agree wholeheartedly with the idea that I'm a liar.
It's possible that it's something my mother managed to infuse me with - she very rarely gave me the benefit of the doubt, and would frequently tell me she was "up to my tricks," very much the kind of stance that a policeman might take in an interrogation, trying to sap the suspect's feeling of credibility just in case they're making it up, so that if they do happen to be lying, they're more likely to crack.
And I suppose if a kid is told over and over that they're dishonest, they would start to internalise the idea, and it might come back to bite them in later life, without them ever knowing what was going on. But it's hard to know, and I find it very difficult to think about coherently, which I gather happens when trying to look at something buried in the unconscious.
If I see the situation coming, I often find I can steel myself against it, and then I can get quite resolute.
