I walked into SIS on Friday and all of the lights were off. There were no teachers around, and I couldn't see any other students. I checked my phone and there was no service or WIFI. I heard the doors lock behind me and so I was scared. Then, I saw something that is completely black but with body shape. The background was foggy and blurry until I can't see anything and I walk towards it. The black thing there whispered, "who come in and who will die! " I cried. I answer him back I asked "who are you and why are you here?" It whispered again, "I'm the mighty spirit that live here already for 10 years!" I was shocked. I wanted to run away but the door was locked, the spirit came towards me again, and I screamed. Then awhile, the spirit disappeared. I ran out of the area after that. I called my mom to come and fetch me home. I explained to her the whole story and I almost fainted. The next morning, I checked my calendar and it was summer break already. And I just noticed that the whole story was just a dream.
