Can trauma cause you to block out a particular person?

[storyworld]

I've been working through a book that encourages readers to journal on past relationships with their parents, and I realized I have a few recurring images of my mother no memories, prior to about age 15 or so, of me interacting with her. And in relation to occurrences that others have told me about, I have a vague sense of that event, but not of me participating in it.

It seems to me that trauma causes such a myriad of problems that I can't imagine why it would not be able to cause you to block out a particular person. That's based on my recovery stage today.

Maybe the vague sense of an event w/o remembering yourself participating in it is some form of dissociation from back then?

Thanks, Blueberry, I appreciate you taking the time to respond.
