I don't care if you laugh

I'm writing this knowing I might get laughed at. Because it was genuinely terrifying!! This happened when I was in middle school. That night, I was so sleepy but really had to use the restroom, so I stumbled my way to the toilet while half-asleep. After I finished and washed my hands, I headed back to my room... On the way, there was a mirror, and I glanced at it. Standing under the dim hallway light was a woman with long hair... I almost screamed, but When I looked closer, it was me. My eyes were half-open from sleepiness, with a vacant expression. Back then, I had hair down to my back, and it was all messy from just waking up. I was so startled by my own reflection that I almost screamed... My family laughed when I told them in the morning, but it was really scary.
