Every time she woke up, she would hear that weird sound at a fixed time, and her mind would keep flashing back to that strange place.
Late one night, she woke up from her dream and found that all her roommates had mysteriously disappeared, and the outside of the dormitory turned into an unknown teaching building shrouded in gray fog. There is no one here, only the cold system prompts on the radio:
"After 23:59, they will start to move."
She was forced to survive in this teaching building and found that every classroom was filled with dead and alive people, and the second floor seemed to not exist, and she could not find the entrance no matter what. The only person who accompanies her is the big yellow dog in the dream - but is it really credible?
