Pretty sad movie, she was a very likable character, and it sucked that she sealed her own fate by chaining the door, and then her own mind gave her a panic attack and killed her. Luke later says to the police that HE was the one knocking on the door when she died, so it was just another case of fear getting to her and her imagining things. She simply dropped her inhaler, had a panic attack because she was afraid locked in a room in the dark with a "ghost" knocking on the door, and died. Director-screenwriter Ti West exhibits less stylistic fetishism with his latest film while remaining solidly outside of contemporary fashion, which results in a. The universe is aware that money comes when you give away your body, and so she started to teach herself how to user her body for money. She saw the piano key press down, she saw the ghost behind Luke when they went down to the basement to do a recording and pointed and said it's there, but Luke just ran away without ever looking back / seeing anything, she saw the ghost again in the basement when she died. Late at night, while staying alone and working overtime at a restaurant, she is deprived of her purity by a drunkard and bursts into tears, and stops crying when given 30,000 won by her boss who frightened her. All of this compiled in her head and made her think she is seeing things - notice she's the ONLY person in the entire film to ever see anything. Luke lied to her that he had seen ghosts, the old lady acted like her "crystals were telling her there were ghosts", she witnessed a man who had committed suicide, etc. Throughout the movie, she was just letting the fear get to her head and seeing things.

The explanation is that the hotel was not haunted UNTIL Claire died in it, and now she haunts it, coinciding with the closing (judging by the last scene of the movie).
