This story is one of the more recent. It happened only a few months ago.
Me and my partner had a wee bit of a fight so I decided to go for a walk to calm down a bit. I ended up in the park around the corner from my house. I was laying quietly on the slide staring at the sky when all of a sudden I started hearing noises. I ignored them as it was late at night and I'm scared of the dark so I thought it was my imagination and went back to staring at the sky.
The next thing I heard something that sounded like someone walking through leaves, which was strange as there were no leaves on the ground at this park. As I turned my head to the right, I saw a dark shadow of a dog walk past. It was the same size and build as a Greyhound. I could perfectly make out its tail, ears, snout and body, but could only see 2 of its 4 paws. It took 2-4 steps then was gone. The strangest part was, usually when I dog takes 4 steps you see all 4 paws, but even as it was taking these steps, I could only see 2 of its paws. Again I thought my imagination was playing games so again ignored it. Until I heard a dog panting.
When I sat up and looked around, I saw the same shadow dog on the opposite side of the park. At this point two rabbits (these I knew were real) came running across the park, looked towards where I had seen the "shadow dog" and froze. I sat there and watched them for nearly 20 minutes, and they didn't move. It was at this point that I felt uncomfortable and like I was being watched and walked home, making sure I left from the opposite side of the park to where I last saw this unknown...thing.
I told my partner about it the next day and he looked at me like I was crazy, so I'm not going to be surprised if you all think I am too.
