If a person has strong unfulfilled wishes when he dies, his consciousness will collapse into an "obsession space" - the appearance is the most familiar scene during his lifetime, and time will always loop in the last period of daily life before death. The deceased repeats their actions here to maintain their existence until the obsession is dispelled or the space is broken by external forces.
Lin Zhiwei's obsession space is the "work process" that she repeats a thousand and seventy-three times a day: putting away lunch boxes, making tea, and watering three pots of green plants. She thought she was "living", but in fact she was using this ritual to nail herself to the gap of death.
Intention: Obsession can be a cage or a key. There is no good or evil in obsession itself. The key lies in the "object" of your obsession. If you are obsessed with "escape", space is the cage; if you are obsessed with "going home", obsession is the key.
