Sounds like the closest thing to a flashback, research flashback they have some origins in your memory although you say you don't have memory...Talking about it session came maybe make that memory seem more real to you instead of downplaying it and wonder why who ever done this too is health or not....That kinda doesn't matter.....Sometimes, people just get mad doesn't necessarily mean they are mental health lol...Although, I get what you are saying, when we as adults enter therapy you question everyone's sanity growing up that you was around especially the immediate family, especially if there is cycles of abuse from their family . Hopefully they are safe enough to keep that relationship now matter how mad you get
