Our Campus Haunts

Despite being small, my school is the oldest and most famous in my hometown. It only has a population of 300 students and 25 faculty and staff members; it's not that it's not a great school, but few people can afford to send their children here. The building is very old but also very elegant. It looks like an 1800s mansion, with a beautiful garden at the front and a line of oak trees from the gate to the building.
It is also haunted.
Even though it is prohibited, some of our teachers couldn't help sharing their ghostly encounters with us.
Mr. Eddie Mondragon told us this:
"It was examination week, and I was working late to print all the test papers. I ended around midnight. As I walked out of the office, I was startled by a little boy running passed me. I thought it was one of our students, so I chased him. He stopped at the level four classroom. He looked at me and gave me a smirk. I was about to approach him when he just disappeared into thin air right before my eyes. It scared the hell out of me; I ran as fast as I could to my car and drove home."
Ms. Judith Lee told us this:
"After examination week, I was doing my records on the level four classroom around 10 pm when I heard someone humming near the door. At first, I didn't bother to look because I figured it was probably one of my fellow teachers, so I just continued recording. After a short while, I started to feel really cold, and the humming turned into a scary sound. I looked up, and to my horror I saw a 16-year-old girl wearing a bloodied white dress. She had a severe cut on her neck. She was banging her head on the wall, crying and humming at the same time. I wanted to scream but I couldn't -- I felt paralyzed. The next thing I knew, I woke up in an all-white room -- the hospital. I was excused from work for three days."
Mr. Joel Samuel told us this:
"I was doing my laundry on a Friday night (I live in the school dormitory) when I felt a cold wind brush through me. I looked up and saw a woman wearing a white nightgown pass by me. I thought it was just my fellow teacher; I even asked her why she was wandering the school campus at night. She didn't reply, so I looked at her again, and it was then that I noticed she had no feet and she was floating. I froze and left my laundry undone."
