My Hospital Dream

A girl has woken up in this weird place not able to remember what happened before. She noticed that she was in a hospital and she makes her way to search for someone... anyone. As she wandered her way she didn't know if she'd find anyone and she makes her way to the roof to have a better look at were she is. When she steps outside she is acquainted with this unfamiliar comfort. She is alone with her and this feeling until someone speaks. Does she know this person? If she did why are they there?
