If one is capable of pulling off some self-hypnosis, alter your own memory, then take a polygraph test, would that stand a good chance of coming out negative? Can one deceive one's self into believing their own lies? As revealing as this can sound, that is actually a workable method to lie, in my own experience. I can suspend my own disbelief long enough to tell something untrue and seem as though I utterly believe it's true. I know I'm highly resistant to that kind of deception in return, or altercations of my own memory. I don't believe anything someone says I did, when I don't think I did it. I require evidence. Otherwise, I'm a stubborn skeptic. Try and convince me all you want about whatever you think is real, but I reflexively only believe what I think is real. It's my reality, regardless of opinions. No one makes up that reality but me, when it comes down to it, so I choose to believe what I want to. Anybody else can go fuck themselves. I don't ask others to believe me. It's like some sort of fucked up religious dogma, trying to impress on you a perception that isn't consistent with your own.
