Why did I dream I was put into an asylum?

The dream just started with me in front of a mansion like house. I remember saying to the person beside me "The souls are in pain. They shouldn`t be here. They don`t belong.". The walls were white. All the people I saw were surrounded by colors. I think they`re called auras. My black dress was exchanged for a white night gown. My long reddish dark brown hair was cut to my shoulders ( like I have it now ). I don`t remember much from the dreams. But, I remember a dark room with an old fashioned white bathtub in the middle. Five people carried me fighting towards the tub. One was my older brother, one was my best friend who`s like a sister to, and one was Ryan George ( my secret crush since 8th grade ). I saw Ryan in the dream before. He was walking toward the building with no emotion shown on his face. They threw me in the tub and began holding me down. I fought them. Once my head was above water I screamed "Demons. I`m not your princess! Leave me alone!". Then it switch to two years later. My hair was to my hips again. I was under watch at a out door movie theater. I managed to run away. A little boy followed me and begged me to take him with me. Then It switched to a walking bridge. My dog Gizmo was with me, but she kept disappearing. Then Ryan Maynard ( friend and one of my crushes. ) brought her back. Then I woke up. My worst fear is being put in a mental institution. Also, at the begining of the dream it looked like the early 1920. And, at the theater it looked like modern day.
