Sounds like you have several ugly little snippets of memories. I can see how, if you weren't allowed to lock doors and your mother would have your father take a screwdriver to any you managed to, etc. that that would be a theme in your life so you'd remember this other, first memory too, of the friend's father beating on the door and yelling and perhaps getting it open. That would be extremely scary! You don't know what's going to happen but it's the sort of memory that makes for nightmares!

Kids think and remember things so strangely anyway. I don't like (I'm nearly 60) to be at other people's houses, they can be relatives or friends, doesn't matter, I'm uncomfortable at other people's houses, especially if I'm alone. I finally figured out after a zillion years of therapy it had to do with my stepmother, who married my father a couple weeks after I turned five; she had to take me with her everywhere because I was so young and not in school yet. And, in the beginning, I didn't know anyone, all these people, including "relatives" were new to me. So, when she'd leave me to play with my "cousins" I got to worrying about whether she'd come back and get me! (My mother who was sick all my life and unable to care for me, died when I was 3 and my father had to work, of course, so there was sometimes spotty care for me and my 3 older brothers). All these strange people and not driving yet :-) so didn't know directions to houses, etc. so I would never really know where I was so even though I was totally safe (was never abused or mistreated by relatives!) it was very scary for me and I never really understood it until recently. As a teenager I never really babysat and the couple of times I did, I was always miserable at the other person's house. I even have trouble now, going to babysit my grandchildren! I just feel like I don't belong in other people's houses.
