I'm not an expert on dreams at all, but I'm very familiar with how my own dreams work. I can see how they work, and it's easy enough for me to figure out where any of them come from. I don't know if that's because I'm relatively free of "underlying issues" because I just kind of deal with things head on. (My dreams were a little more complicated when I did have "issues" associated with a messy situation surrounded my mother's death). Anyway...
A whole lot of my own dreams come from nothing more "deep and meaningful" than my having had some thought or heard or seen something within recent days that had a momentary impact on me. The impact may have been something I barely noticed, but once I have the dream I recall having had at least some fleeting impact with regard to whatever the minor incident/thought was. I could hear something on the news, see something/someone in a store, make a remark to someone in conversation, whatever... For that fleeting moment I might have some quick thought. I've never dreamed what you did, but if I did it would probably come from something like this: Say, I heard something on the news about a mother who abused her child. For a quick moment I might think/say, "If I ever had the urge to hurt my child I'd leave." Maybe in the same week I'd have a conversation with someone about worrying that my divorce hurt my children Then maybe in that same few days I might see someone doing something on TV.
What happens with me is that my dreams will take all those fleeting moments of "noticing" (impact) and maybe having a quick thought/response that was equally fleeting; mix them up, and come out in the form of a "story" (or scenario).
I can see how if you have abuse in your background it might be lurking in your subconscious, waiting to show up in some way in a dream; but I'd think there's also the chance your dreams could either have come from something like I've described and/or something like I've described combined with your background.
An example that I can see being a possibility might be that you heard, or talked about, the idea that formerly abused kids sometimes grow up to be abusers. A buried (or open) concern about that, and maybe that mixed in with other things that have gone on in your recent day-to-day life, could (I'd think) contribute to that kind of dream.
Basically, what I've seen happen pretty much all the time, is that those quickie, fleeting, images/thoughts of recent days seem to be "put in one container, shaken up, sometimes attached to a concern I have, and then dumped out in the form of a story/scenario.
