Decoding the Theory of "Horror Hotel"

The following is the story I understood in my light sleep: (Some may be wrong, please point it out)

The hero (male for short) → dreaming that the heroine (female for short) is dead → waking up (indoors).

↓

Female → Dream of male death → Wake up (indoors)

↓

The two received the task → went to the hotel → the dead couple appeared in the carriage → men and women lived in separate rooms → witnessed the death process of the dead couple.

→ Two people were killed by the murderer → Wake up (in the car)

↓

Arrive at the hotel → men and women live in the room → kill each other → wake up (in the room)

↓

Received the task → refused to leave → went from the bar to the food stall → learned that he was dead on TV → saw rude aunts and stupid decorators.

→ (Suddenly no one) Two people fled → Fog scene (suspected to enter the inner world) → Get on the bus → Dead couple appeared, "We are going to disappear"

↓

Back to the real world (is it a parallel world? ), the two made up and met a dead couple on the elevator.

Core theme guess:

Those two killers come from mutual suspicion between the hero and heroine, but there are no such two living people (long dead) ... The killer is just a figure who incarnates negative emotions such as suspicion and jealousy, and is cruel and powerful (so the male killer is weak in front of the male killer, but he is not really weak, but he just can't compete with his own heart) ... But I think it is a good ending in the end (although it is not whether the protagonist is really dead) ~ ...

Various doubts:

1. The whole film needs to be explained ~ ~ I don't know if all kinds of scenes are true or false ~ ~

2. In the fight, I think that the man and the woman have every chance to kill the murderer with a knife ... but there is no such thing ... it's a bit fake! ! !

Does the scene of that rude aunt and the decorator have any special meaning?

4. Did the man and woman die in the real world?

Summary:

1. It's not terrible at all ... I felt a little sleepy at first ... which means it's hard to get into the play. ..

2. Gong Mi acted well ~ but the scene of being chased was a bit exaggerated ... My friend and I laughed with malicious intent. ...

Reminds me of Silent Hill and an American TV series (that is, the TV series where people say "help me" and then go back to the past until they successfully save people) ... How do you say ... there is still a gap in level. ...

4. Not bad idea ~ ~ Come on, domestic horror movie! ! !

It's in the horror film post bar. You can watch it yourself.
