I remember having this dream when I was a lot younger that involved me and my cousin being forcefully operated on by some guy in a trenchcoat with a crazy look in his eyes.
It got better later on when it turned out to just be a horror film shoot. I woke up with a confused look on my face. Weirder still, in later dreams I could see him in the background operating on folk and turning them into Pokemon. Which was strange cause this was around the time I started playing Pokemon Mystery Dungeon.
