Past lives yet no memories of how I died

So I have past lives of my kins, yet I don't know how I died. like I have the memories, and everything yet I don't remember how I even died. It's like I didn't even die and I'm just an au with the memories of them. It's confusing, like I has the memories yet I don't know how I died. (Andrew and Ashley are an expectation since well- yeah. I know I died as Andrew by uhh ending where I killed her. as Ashely the building ending) anyways! is it possible to not have died yet still have the memories of the past lives?
