What is the ending of Ghost?

The ending of Ghost is that Ben Benjamin enters a mental hospital, and the last scene is that Ben Benjamin's later girlfriend visits him in a mental hospital. From the reflection of the glass, it was found that the dead woman had been riding on Ben Benjamin's neck.

Ghost is a horror film directed by Masayuki Ochiai and starring Joshua Jackson and rachael taylor. This film is a remake of Thailand's film of the same name. It tells the story that the photographer and his wife knocked down a young woman while driving, but later the woman disappeared. The couple who thought that things had passed like this began to have strange things one after another.

The newlyweds Ben (Joshua Jackson) and Jane (rachael taylor) are photographers. They came to Japan for work. After arriving in Japan, they all drove to Tokyo. On the way through a ghostly forest, the car suddenly lost control and hit a girl. The girl was bleeding profusely on the spot and lost her soul. Both of them were beaten unconscious. I don't know how long it took, but when they woke up, they found that the girl had disappeared. Only a large area of blood on the ground proved that this was not a dream. Although my heart is full of doubts, there is nothing I can do-perhaps, things have passed. So, they continued to start the engine and came to Tokyo to start a new life. However, strange things began to happen around them. Ben always found strange white spots in his photos, which puzzled him, but Jane remembered the car accident when she first arrived and thought it was the ghost of the dead girl.
