Bathroom Ghost

This is where it starts off: My brother, my brother's girlfriend (now ex), my mom and I were in my mom's car. I had to go to the bathroom, and luckily we were parked in either a burger king's parking lot or a Carl's Jr parking lot.

So my brother's ex-girlfriend took me inside to go to the bathroom. When I had already gone, I stood up to grab the toilet paper. I heard like a little girl humming. I looked around to see what might have been causing the humming. There were no fans, radios, nothing that could sound like a little girl humming. It sounded like it was coming from the corner of the bathroom.

The bathroom was a small square room. And there was absolutely no one except me in the bathroom. I hurried up what I was doing, washed my hands, and ran to the door as fast as I could. I tried to open the door, but it was locked (stupid me). I unlocked it and ran outside.

My brother's ex-girlfriend asked me what was wrong when she saw me panting. I said nothing. But I ended telling her what happened. I can see she didn't believe me because she looked at me like she didn't believe me, and that I was crazy.

I'm not sure what it was that was in the bathroom with me. And it certainly wasn't my imagination. So can someone please explain to me what it was? That would be awesome. Thanks for reading my story. I hope you enjoys it. Peace.
