About 10 years ago when I was 6 years old I attended a local summer camp at the YMCA. At the camp I had lots of friends that were my age and we all got along very well. It was just another regular day at camp where the camp counselors would bring us kids to a nearby park that had nothing more than a large gazebo, flower garden, and public restrooms.
The restrooms were always known to have paranormal activity, I had previously heard stories of it being haunted ever since I went to the camp. When we all got to the park the counselors told us we could do whatever we wanted as long as we stayed inside the park and not wander off. But the only problem with that was me and my small group of friends wanted to check out the supposedly haunted bathrooms just outside the park. We were afraid that if we would go to the bathrooms, the counselors would notice that we were gone and take away some of our camp privileges. My friends and I thought of a plan. The plan was to quickly run over to the bathrooms when the counselors were not paying attention and go inside. I thought this plan would be unsuccessful but it wasn't. When we got into the bathrooms I was gasping for air because of how fast I was running not worrying about anything paranormal. Once I caught my breath my friends were walking around, looking in stalls just to see if anything was out of the ordinary, while I was in the corner by the sinks and mirrors with an eerie feeling, I can't really explain it but something just did not feel right, and it smelled very bad in there (of coarse because its a bathroom).
It was a very large bathroom with about 10 stalls and my friends had checked every stall and everything was how it should be, nothing mysterious or weird had happened until we were about to leave the bathrooms. As my friend just got done going to the bathroom he started to wash his hands. Me and my other 2 friends were talking about how fake the bathroom legend is and how it is nothing but empty stalls, just when my friend that was washing his hands screamed vigorously while looking at the mirror. It startled me and my other friends because we did not know what he was screaming at, but when I looked up at him in the corner of my eye I saw a dark shadow figure in the shape of a human behind him in the mirror. All of us must have seen the figure because we all sprinted out of the bathroom screaming. We ran up to the counselors and told them what happened. The counselors were not mad at us, they actually felt bad for us because we were so shocked from the situation and crying. I like to be scientific about things and try to find explanations but I could not explain this occurrence because no one was in the bathroom except for me and my friends. This is an experience I will never forget because it is something I can truly not explain.
