Me, my mother and father were on holiday, in some holiday home or another that I didn't recognize from real life, and me and my Dad were massacred/shot whilst staying there, whilst my mother survived the onslaught. I died and I had a warm feeling of travelling through the cosmos.
When I awoke, I was in a kitchen full of people, in some alternative reality, and one of the people in the kitchen, who seemed to be the leader of the group of people, said something to the effect of:
"I've managed to carry over most of the people over from the previous reality and we're all here now apart from sadly, *insert names* who didn't make it."
I looked down at my body and I was several dozen kilograms lighter, and could walk very fast to my surprise. Through a temporary vision, I saw my previous death in the previous reality was age 42 and I felt horribly guilty that I had left my mother behind who had survived and I started crying.
I went into another room parallel to the kitchen in the new reality I had been placed in after death in the previous one, and I mentioned to the leader guy who came into this room from the kitchen, that I wanted things to be the same as they were before, me, back with my family in the original reality. After some struggle, I managed to convince him to send me back.
He sent me back (or so, seemingly, was the intention).
I woke up again, this time, as a fat child instead of an adult on an upstairs landing area between bedrooms and my Dad, appropriately younger relative to my real life age, said we had both had a shared dream where we had been shot, and that I was back home now and that everything was okay. Evidently I was in a house I had lived in, but both my Mum and Dad were a lot younger than they should have been and the group leader was gone from before, I felt alone now and that I was stuck in this 'wrong' incarnation of reality. And then I woke up shortly after. D:
