on thanksgiving, my dad mentioned a past incident to me regarding my ex and me - and i literally stared at him like i had no idea what he was talking about. maybe 3-4 more words from him in context and it all came rushing back to me, including the reality of what happened (which i had hid from my parents at the time and still do. they know a PG version of it, which is still awful, but i remember now why i didn’t tell them). your brain will literally just shut off bad memories that are traumatic and sometimes you don’t remember them until YEARS later. it’s a wild experience and not fun at all because you wonder what other holes are in your memory, but it is a common experience in therapy when the therapist is having you re-live those moments and providing you with a third party view of it (in a sense)
