Looking for movie names

Introduction to the film:

During World War II, Grace lived on an island with her two children, Ann and Nicholas, waiting for her husband to return from the battlefield.

They live alone in a big apartment. Although the house seems too big for a family of three, Grace prefers it so that the two children can rest in peace. According to the doctor's regulations, they can't receive sunlight and can only stay indoors. In order to ensure their health, Grace even made many rules: for example, all curtains must be closed and doors must be closed immediately every time they are opened.

Life is a little inconvenient because the servant disappeared for no reason not long ago. One day, when three people came to apply for a servant, Grace immediately agreed. These three people are Mrs. Miller, the nanny, Mr. Teto, the gardener, and Linda, the mute maid.

The arrival of three people seems to add a bit of life to the house. But a series of strange things began to happen. The door will automatically close and the piano will automatically ring. Ann even said that she saw a man named Victor in the house.

Grace gradually felt that the house was surrounded by a strange and mysterious atmosphere, and she fell into anxiety. Everything became confusing. Is there really anyone else in the room besides them? Those three servants seem elusive. What's their purpose? In fact, Grace is an eccentric woman, and she is a little hysterical in this environment.

The nightmare began. Grace and her children seem to face supernatural forces. ...

Post-view explanation:

That mother is actually a ghost. She had a nervous breakdown after losing her husband, killed two children with a pillow while they were sleeping, and then committed suicide. Including the housekeeper and nanny, are ghosts.

The reason why the mother is haunted in the house where they live is because she is too attached to her feelings before her death, thinking that she and her children are normal living people and the owners of the house, and treating those normal people who live among the dead as ghosts and intruders in their home.

Grace and her two children died at the beginning of the film. They were ghosts and couldn't see their servants.

Because people and ghosts can't see each other, but they can feel each other occasionally, just like the part where Grace hears the piano.

They didn't know they were dead, and the three servants who came later were ghosts, in order to tell them the fact that they were dead.

The uninvited guests they say are actually real people who want to move in after buying a house.

The last four people talked around the table, because one of the witches (the oldest woman) noticed that there was a ghost in the house, so the whole family moved away, but the new tenant will buy a house to live in recently.

At the end of the film, they no longer felt terrible. But I guess they will feel confused and helpless after they are no longer afraid, a kind of abandoned confusion and helplessness. We will always feel fear, fear of our world.
