One more from the collection that I remembered. Surreal horror, not so much a creepypasta. The author explained it was about his childhood horrors about the man who put down his dog while he was away at school.
>When I was a young child my first dog, Callie, had to be euthanized due to an aggressive cancer. My mom decided to have it done when I was away at school and though I never saw the man who killed my dog, I had terrible, vivid nightmares about this imagined foe for months after the fact. This is the Dog Killer of my dreams

Agree completely. >>41051400 fits in a similar category. Anything where you have to briefly doubt reality or memory, or even the honesty/sanity of others; it works especially well through the haze of childhood. I don't find either story necessarily scary, but they're both unnerving.

Semi-related: one thought that used to scare me as a kid was of seeing someone in my second-storey bedroom window. It was easy to imagine a face there, but that implied it got there somehow: climbing the wall or flying: a dedicated intruder or something supernatural. A simple fact (a face in a second-storey window) can imply something much more horrible.
