Written Confession: Crawling 'The Grudge' Girl in the Mirror

The following written confession was shared via Reddit by Trick-Compote90011:

Let me preface this by saying I don't hallucinate, nor am I psychotic. This has been bothering me since it happened a couple years ago. Before this incident, I used to leave the door to my room open, which has a full-length mirror fastened to it. I went back upstairs one afternoon to grab something from my room; the lights were off upstairs, but it was still daylight outside, so there was a sufficient amount of light coming in through the windows. As I was walking the last few steps up to the third floor, I glanced into the mirror that was on my open door. It appeared that behind me, crawling up the stairs, was a pale, thin girl wearing either a dirty white dress or oversized tee shirt. She had long, stringy, black hair that was greasy and plastered across her head, so that I couldn't clearly see her face. You know what? She dead ass looked like something straight out of The Grudge. Of course, I turned around to look down behind me and there was no;one there. I haven't left my door open since. I like to think that I was just imagining things, as I never saw anything before or after this event.
