It sounds as though you often dissociate, and that does alter your perceptions. Sometimes I wouldn't be able to hear clearly--like I was far away from the other person--and so I would raise my voice, but it wouldn't sound that way to me. And sometimes it would feel as though the other person were shouting at me, or an emotion like anger was heightened, but the reality wasn't that at all. It was my anxiety changing how my senses worked. It wasn't a memory issue, but a sensory difference because of dissociation.
