lingering dream 1.9

A girl get a therapy because she's been acting strange. She's been sleeping in a bath tube. Her mom is worried. Worried that her daugher might accidentally drown.

The girl thinks she was kidnapped once when she was young. The thing is she was with another boy at that time. She think the boy had been hurt or died and she left him behind. She don't know who is the boy, is it random boy who is unfortunately being kidnapped too, her friend or her brother. She think, she is close with the boy, although she don't know whether she's already close with the boy or they got really close because of the kidnapping. She don't have brother or boy close friend, that is why she think something bad had happen to the boy. 

She tried to figure this out alone, because she think, the worst scenario is that her mother was her kidnapper.
