I have A LOT of strange dreams, i have a few written down, so I might be back to this thread later.
One of my strangest dreams of all time was a few months back, while I was still in university. I was dreaming about going through my life as ordinary in my family home, only to find a dead skinned human body laying face down just by our back sliding door. It wasn't posed, definitely a 30-something year old man, uninteresting in appearance other than a little chubby. He was sliced cleanly in half along the coronal plane all the way down. It wasn't really bloody, but I could tell the halves were mismatched/slightly ajar? (img for reference)

It was really startling to see, but none of my family living there would acknowledge it, indirectly or when I would mention it. I mentioned calling someone to take care of it, they'd say "Oh yeah sure, I'll get on that". The dream went into a timelapse over the weekend of it just sitting there, all of us making efforts to walk around or avoid touching it. It didn't degrade over the span of the timelapse either.
I woke up before the timelapse was over, and I never really got any explanation for it. This dream stood out as weird because normally my dreams aren't this graphic in content.
Edit: I checked my message logs, and it turns out I had this dream exactly one year ago today
