What is the final ending of Snow Mountain? Who's a ghost? Man and his teammates (this is a movie from China)

In fact, among the domestic horror films, I think this film is already good.

First of all, let me explain before the spoiler:

1. This is a movie with a circular plot, which means that the beginning of the movie is actually the end of the movie, and it goes on endlessly.

Second, at the beginning of the film, the heroine said that she had altitude sickness and headache (the director paved the way for the dreamland/reality behind)

Third, black plastic bags, I think there is only one situation that can be said in the past. Black plastic bags are the only thing that connects reality with the future; In order to connect the beginning and the end of the film, the director showed the heroine another car she was chasing when she entered the mountain. I define it as: reality sees the afterimage of the future and pays attention to the afterimage here. So the heroine can't see another self after getting off the bus.

The actual story is as follows: Time: On May 4th, the mountaineering team drove into the mountain; On May 7, four members of the mountaineering team lost contact; From May 7th to May 9th, the heroine dreamed; May 14, video shooting (the movie lasted about 79 minutes, and Xinyi said she slept for 5 days).

Plot: On May 7th, the mountaineering team climbed the mountain, but they couldn't be contacted afterwards. Xinyi began to dream on the evening of the 7th, dreaming that three climbers were dead/1 (each said his own words), which made Xinyi lose his judgment. Then the climbers began to kill each other, which made Xinyi's spirit begin to wander. Nobody believed it. After that, she was "woken up" by four members of the mountaineering team (here is also a hint, implying that all four members of the mountaineering team are dead). In fact, Xinyi didn't wake up, still dreaming. Then Xinyi dreamed of Ji Li Ann and Lao Wei. According to the information in the first dream (Li Jian likes Xinyi), Xinyi quarreled with them and thought that Shanghai was harmed by them. As a result, Xinyi was killed by Lao Wei; At this time, Xinyi really woke up on May 9th. In order to determine whether it is a dream or not, Xinyi cut her wrist to make sure it is not a dream. Because of altitude sickness or excessive blood loss, Xinyi fell asleep (not a dream), and he saw Ji Li Ann and Lao Wei again. Because Xinyi cut her wrist and caused pain, Xinyi firmly believed that this was the reality. Xinyi thinks that these two people hurt Shanghai, and because they were killed by Lao Wei in their previous dreams, Xinyi killed Ji Li Ann and Lao Wei as soon as possible after discovering the change. Then Roy and Shang Hai came back. Xinyi thought she had killed someone after listening to Roy and Shang Hai's reasons, so she took Shang Hai to confirm the body, but the body was gone again. This time, Xinyi questioned her own cognitive world. He still believed that he could wake up from the tent again, so he chose to jump off the building himself. In fact, Xinyi died when she cut her wrist on the 9th. May 14 When she got up to shoot a video, Xinyi was actually dead and didn't know how to sleep for five days. When he started the car, he found that he could see blood and bad parts that he had never seen before. At this moment, he realized that he might be dead. At this time, she happened to see the scene when they entered the mountain. Xinyi wanted to stop this from happening, but Xinyi found that no matter what. Xinyi watched them enter the mountains and started the cycle again.
