WAS THIS REACTION OUT OF TRAUMA OR OVERREACTION?

I come from an emotionally/verbally/physically abusive home...where I was abused directly. In fact, I'm just beginning to realize I have wings after feeling for 23yrs that I never had them. If you come from that type of home, you'd prbly understand. My family finally had enough of it wt dad and we reported him to the police (domestic violence) like a month ago. So, yesterday I had to go to a locksmith shop and I felt a bit scared and quite uncomfortable with 2 men(1 owner and another customer). They were joking with me and what not, but for some odd reason I was very cautious with them and had no sense of ease with them. I just got really tense and at some point blanked out. The owner kind of reminded of my dad...like asking "who did this damage and who did that one?...the way my dad would always find a way to find out who did what and blame on everyone.The way he talked to me was also kind of rough and loud. It wasn't pleasant. I didn't feel comfortable with him at all. The damage was fixable but him asking it the way he did brought me bad memories. Besides, his dog was very submissive...which isn't a good sign because dogs will do that out of mistreatment. Confident dogs will not be extremely submissive to other people like that.(I've had dogs...). Btw, im 23.
