This story is an experience I had when I was in my 1st year of high school. The school I attended to is one of the oldest running schools in our country and is already well-known in the field of ghost haunting and the paranormal.
We were having our P.E. Exam at the school's covered court around 2:00 in the afternoon and I've just had my turn on the exam, all sweaty and out of breath. I went over to the bleachers where I left my bag to get the hand towel I brought specifically for this afternoon's activity but realized I had left it on the armchair in my classroom when changing clothes. I immediately went to my teacher and asked permission to go back and get it as I was literally soaked from the P.E. Activity - and she gave me 3 minutes to do so.
Our classroom is located at the 2nd floor of our building. I had to climb 2 sets of stairs before making a left and arriving to our classroom. Also, each stair had a saint statue since I studied at a Catholic school.
Once in there, yes! - my hand towel was where I thought it was so I just grabbed it and headed back to the door right away.
Since our building was a 3-storey building, a stairway is on my right when heading back down. As you all know, I was only given 3 minutes for my errand, so I sprinted from my room's door to the stairs going down when I noticed it like a flash.
At the top of the stairs going up to the 3rd floor, a black figure stood. It was beside the statue if St. Ezekiel. At first I thought that it was just another student since the library was located at the 3rd floor but it was wearing something long down until the ankle. Our uniforms were down until 1-inch below the knee.
My heart raced from the running I did but a part of it was what I saw which I am unsure what it was.
I just kept it to myself until 2 days later when we had our Religion subject and had to share something in class - something either inspiring or an experience (extraordinary) we had ourselves or from someone we know.
When it came to my turn, I told the room and my Religion teacher (which was a seminary graduate and was a previous seminarian in our school in his time).
After sharing, my teacher then told all of us that this story was not new.
There was a girl back in the day with very poor health. My teacher said that she was very sickly she had to take a week out of school but manages to come back when feeling okay. She kept up since 1st year until her last year. Until sadly, she passed away mid-semester on her 4th year.
I believe it was her spirit sticking around wearing a toga, longing to have graduated.
There are many more stories to tell you guys and I believe other stories like this. But this was my first experience concluding doubts I have in mind so wanted to share it first.
