Explanation
A musician lives with his wife in a small house in Dallas, Texas. They lead a happy life together, and are looking for a new home and planning their move. She tells him that before she moves away from a place, she likes to hide a note for herself there; in case she ever returns. They occasionally hear strange noises in the house; one night they hear a loud bang in their living room, which contains a piano which came with the house. They cannot find the source of the noise.
The next morning, the husband is killed in a car accident in front of their house. At the hospital, his wife views his body before covering it with a sheet. The man awakens as a ghost, still covered in the sheet, and wanders through the hospital, invisible to others. A door of light opens before him, but he makes no attempt to approach it, and it closes. He walks home and watches his wife grieve. Through the window, he sees another sheet-covered ghost inside the house next door; the two ghosts wave to one another.
One night the wife arrives home with a man, whom she kisses. The ghost hurls books from the shelf and turns lights on and off. The wife later listens to a song written by her husband. She eventually decides to move out. Before she leaves, she writes a short note and hides it in a gap in a wall. The ghost picks at the gap but cannot retrieve the note.
A family moves into the house. The ghost watches them eat dinner, play the piano, and celebrate Christmas. He becomes more and more agitated, and the children sense and become upset by his presence. One night the ghost gets upset after seeing a framed photo of the happy family on the piano and knocks it down, then starts hurling plates and glasses from the kitchen cabinet in anger. The family moves away. The second ghost continues to wait next door.
At a party thrown by the next occupants, a hipster explains the premise of the film, positing that remnants of the past, such as Beethoven's symphonies, will linger in the collective human memory long past the collapse of civilization. The man then describes the Big Crunch theory, which concludes that the entire universe will eventually collapse back into a singularity. The partygoers notice the lights flickering.
