Misplaced?

Laney West was a ordinary girl. So she thought. Her parents would always hear her talking to someone in her since she was little. When they would go inside to check on her there would be no one there. "sweetie who are you talking to?" they would ask. "Brenden! Can't you see him?" Little Laney would reply. When she was only 10 her parents took her to a mental hospital and left her there. Still at 15 she insists she's not crazy but they always hear her talking to someone.
