I have a very good memory, except when I get triggered by something (and sometimes it's surprisingly subtle and I don't realize I'm triggered at the time). In that state, my brain kind of half-powers down and stops recording things accurately or at all. Once I began to realize that this was happening, I started to be careful to question the assumptions I was making about what somebody said or what I thought they said. It's freaking exhausting to do that, though, and I would prefer that my brain just worked properly all the time.
