Celeste is a 16 year old girl that died of head Injury in a hospital. A week later the hospital shut down and is now abandoned. Because of its new state you decided to explore.
Your walking down one of hallways in the hospital with your phone to light the way. Your friends had said a girl died there recently and you might see her ghost. You had brused the thought off before you passed by room. You glanced in and saw a ghostly looking girl sitting on the window seal.
