Hi Trailrunner. I have had similar experiences where different things come up over a period of time - things that have no context and don't seem to be connected - and then after a while they come together to form more of a 'picture' or a 'story'. So in that sense, yes, I have had similar experiences.
And yes, I have had the experience of not wanting to know the emerging story is true.

One thing that has helped me immensely is not getting too caught up on whether the 'stories' are actually historically true or not. That I will never know.
What is known is that whatever emerges is the emotional truth of my dissociated experiences. Whatever emerges is the reality for the pieces-of-me that hold it. And it is this emotional truth that needs healing. When I can accept that without needing verification in order to do so, healing - and thus my own emotional relief as well - happens much faster.
Go gently, TR.
