I asked my grandpa once if he's seen a ghost before. He let me sit on the couch and told me this story:
He said "When I was in high school we had a famous ghost story about a girl who roams our school library when she catches you alone. She would start appearing as a student and you would hear her footsteps knocking the tile floor as she walks and even the sound of books bumping the wood as she shelf them. She's beautiful, said in the story, and when you see her face something good happens to you, but it's not that easy to catch a gaze of her. One evening I overslept in the 2nd floor of the library. That was around 6:30 pm as I remember and the school completely closes on 8 pm. To my surprise I was locked inside when I went down the library's 1st floor when I woke up. I banged the door, went looking out the windows shouting for help but no one responded, and I could've jumped if I wasn't on the 4th floor. Later an hour it was growing dark. I heard footsteps closing towards me, and then books hitting a certain shelf. I was sitting on the floor leaning on the 1st shelf close to the window when I saw strands of black hair that flung 5 meters in the air, a back of a female student wearing the school uniform and the tip of her skirt that waved fading in the side of the shelf as if she made a quick turn when she saw me. I shouted "wait" then I heard her footsteps going away fast. I saw her shoulders quickly went pass the gap of the books from the opposite side of the shelf where I stood. I chased her running parallel to her pace and when I thought I'd see her as we reach the end of the shelf she's there going in-between the next shelves as if she skipped space. I ignored her weirdness and checked the door assuming she got in and opened it yet it was still locked. I turned around and saw her again entering between the 6th and 5th shelf. "Hey wait stop. Are you stuck in here too?" I asked in a loud voice as I chase her again. I wasn't sure where to look because sometimes her footsteps would sound closer or farther away or as if she's just right behind me. In a second it silenced. Thinking she might be hiding somewhere I scanned the gaps of books in the shelves trying to see if she there behind them. Searching the next shelf I accidentally bumped a book causing it to fall on my foot. When I tried to reach for it sudden pale hands quickly picked it up stocking it back on the shelf. I stepped back shocked to see it was Hellen, the girl I was developing a crush on who sits beside me in class. I was dumbfounded and we stared at each other for a minute. She smiled at me. Chills traced my body. In my mind something tells me this girl is not the real her. This one's quiet and lifeless. I was about to ask how she got here when my eyes were drawn towards sound of the opening door. When I looked back at her she disappeared. I was frightened and creep high to the skin. I headed towards the door where there I saw a blond girl wearing glasses and pulling a cart of books. It was your grandma Carrielyn 50 years younger doing her job as an assistant librarian. It was love at first sight and God knows how happy I was to see her for I was certain I'm already facing a real person. She was startled to see me and asked me couple of questions while keeping her distance. She even threatened to report me accusing me of trespassing but I calmed her telling her it was unintentional. As we spoke my eyes caught a glimpse of the ghost Hellen up the 2nd floor going behind the closest shelf. Carrielyn got angry asking if I was listening. I followed ghost Hellen with my gaze until she went out the opposite end but it wasn't Hellen anymore, it was already a ghost Carrielyn walking towards the following shelf where she vanished completely. I stare back at the real Carrielyn who's clueless of what I saw, she had an eyebrow raised and she ran through the hallways calling out the security guard."
So why would the ghost imitate Hellen or Grandma? He explained: "Nobody died in the library. What I know was because majority of the students believed a ghost exist in the library she came to existence. Saying she's beautiful was an incomplete reference so when she showed up she copied the person whom I saw beautiful. When I got the crush for Carrielyn erasing my thought of Hellen, then she copied Carrielyn."
