This happened about a year ago, in the summer of 2016. I live in Ohio, and it is usually hot enough to go swimming every summer. We have a swimming pool in our backyard, and on this day, I decided that it would be a good idea to swim in our pool. At that time, I was, and still am, dealing with depression. This causes me to not want to be very social often. And I was having a pretty bad day dealing with it. So when I saw my siblings in the pool, I decided to wait for them to get out before I went swimming. I also didn’t want to swim with them because they tend to be pretty violent in the water, splashing around and dunking eachother’s heads into it to tease each other. I just wanted to go in to relax and think. Anyway, I ended up waiting in the front yard, and a started quietly singing a sad song to myself. Then, out of nowhere, someone went rushing past me. They were running quite fast, and I could feel their feet pounding on the ground and the wind blow past me since they were really close. I looked up, expecting it to be one of my siblings, but instead got a quick glimpse of a girl I didn’t recognize. She had long, dark hair, a white, old fashioned looking dress, and by the sound of her shoes, I think she had flip-flops on. I didn’t get to look long enough to see her face, since she was gone in an instant. I know it wasn’t any of my siblings because none of them have long hair. Or an old fashioned dress. I looked quickly to the pool, only to see that they were all still there. I know this sounds silly, but I thought that she may have liked the song. So I started singing it again. When I finished, I was trying to find any sign of anything, when suddenly, there was a single tap on my back. I spun around, but nothing was there. I tried to brush it off, telling myself that it was just a bug, because I really didn’t expect anything to happen and was getting a little anxious. I decided that I didn’t want to swim anymore. So I went back inside my house to change out of my swimming suit. While changing in the bathroom, I started singing the song again. I didn’t even realize that I was, and it was too late for me to stop myself anyway, because behind me, I heard a loud bang. I jumped and looked at where the sound was coming from. A bottle of shampoo had fallen into the tub. I got out of there as fast as I could and finished changing in my room. I don’t know if the spirit was angry at me for singing, or maybe sympathetic toward me. Maybe it was all in my head. I don’t know. But what I do know is that I don’t sing that song anymore.
