I survived (what was supposed to be nothing but a nuclear bomb going off in a small village in the south of England, but ended up triggering the sun's supernova,) by drinking beer and water (I don't even like the former, but every time I'd take a sip, my body temperature would drop anywhere between 5°c and 30°c).
I'd already seen the aftermath, and decided to time travel to before it had happened, to experience death again and again.
I then read about my 'accomplishments' in a science fiction book, which was dripping with blood, as it was written in it.
When I put the book down, I was in a somewhat familiar house, that was apparently my childhood home.
It was somewhere between time, I think, because there were 'ghosts' of my past that i could interact with if I wanted to. One was my younger self, complaining about the high pitched wailing my phone was making. I could hear it too, once they'd pointed it out, and it caused me to drop my phone and cover my ears. It started off quiet and mechanical, and ended up sounding like a banshee.
Once it stopped, my mother was talking about how I'd been possessed as a child, and I started debating whether I was the demon's first or billionth possession.
I refused to go anywhere near the bathroom, because anytime I did, I would get violent flashbacks of... something?, I think it was the demon being abusive towards me. I remember thinking about how in the memories, the bathroom mirror was the scary thing, because it infinitely reflected, and I was nowhere to be seen. Just an endless void. Every time the demon's face was about to be revealed within it, the flashback would end.
It was strange, because it was as though my memories were completely different to my actual childhood, and as if there was years of backstory behind it.
So, my dream was trauma towards me, but yet, it wasn't my own.
Wait, maybe I was the demon, possessing someone else to get these memories and experiences?
Woah, spooky.
