This is my first time talking about this on the internet. I had this experience that I am about to tell you when I was 16-17 years old, I am 25 now. (Sorry about my English I'm from Romania.)
It was a summer night, me and a friend were taking a walk in the park. We were not looking for ghosts or something, just casually strolling, when we see a girl probably 20-25 years old sitting on a bench in front of us at approximately 10 meters. I didn't really gave it much significance. She was dressed casually and was sitting on the bench with here knees up to her chin, and her feet (soles) on the bench, smoking a cigarette.
We kept getting closer to her and my friend who was besides me kept joking about how he would talk to her and give her cheesy pick-up lines, you know... Like a 16-17 year old.
And then as we were walking and laughing she suddenly disappeared, she just vanished before our eyes. At that moment we looked at each other, my friend asked me, "Look at me, am I stupid? Did you see what I saw?" and I said yes I saw it too, so it couldn't have been our imagination, and I didn't took my eyes of the pathwalk for more than 2 seconds, so she couldn't of been a real person and just walk away because I would of seen her.
After she disappeared we both felt like a warm touch on our shoulder, me on my right side and my friend's left side, like someone was holding his arms around us, but I am not sure if we really felt this touch or we were probably just imagine it from the shock we had, and all the ghost films we saw.
And then my friend saw something in the grass that was slithering and looked like a small snake, I am probably 90% sure that it was a snake. He then tried to catch it with his cap but I told him to quit and run, because at that point I was really scared. So we ran until we got out of the park and still ran until we got in a taxi and we went home.
I couldn't sleep for I think 1-2 months properly and even after months, years I got together with my friend, we would still talk about that night.
I recently saw an article about that park and turns out that it was a military cemetery that was closed in the year 1770, and a century after it was closed, all the remains were transported to a different cemetery, and they built a park. I am talking about the Central Park from Timisoara Romania.
If you have any ideas about what I saw or what type of ghost I saw, and if my experience with the warm touch and the snake have any relevance please feel free to comment. Thank you!
