Dream About Tragic Loss And Search For Answers

I've had this dream in several ways now. The first dream is what started it off completely. I was very young, with 2 children a girl and a boy. A tragedy struck, i really dont remember the details but my children were murdered and drowned. The next time i had the dream, it was all based on my pain of the loss of my children, my boyfriend and i started trying to dig up information and evidence on who might of killed them, while also running into some unexpected information on myself. I had learned that i was adopted. I ended up finding who my real father was and growing a relationship with him. He helped me and my boyfriend cope with our loss and also with the search of finding the person/people responsible. Somehow we ended up getting the full story of what happened and who did it. Down the line, my father who was a directer, created a short film on the story my childrens murder and our miraculous search for answers. And every anniversary my father and the town would put the film on for show for all of us to mourn. The 3rd time i had this dream, i had aged a few years up, and some how my younger self time traveled to my time without any indication of how. She and also her young version of our boyfriend, who was now my ex in my time, came looking for answers on what happened to our kids. Me, my ex bf, sat them both down and explained everything to them. It was a very mournful time to rehash over, we all had to comfort each other in the ways that we only knew how. As the anniversary point started coming up, we asked them to stay and watch the film with us so they could mourn with us, like we have for several years now, as the pain had never gone away. The film rolled, and my younger self and i sobbed and held each other close. In the middle of the film, we were interrupted, by what happened to be the people responsible for the children's deaths. My ex and younger version of him, went on a rampage to destroy them. And thats all i remember
