Nightmare Apartment: There Is a Ghost in My Room!

This is an apartment that does not exist. Only those who are selected by the apartment will come to this apartment in their dreams. Of course, the apartment isn't terrible, it's just... In this apartment, you will receive nightmare invitations from evil ghosts from time to time. Only those who come back alive from the nightmare are qualified to participate in the next nightmare. You mean escape? No, from the moment you enter this apartment, you embark on a path of no return. (Infinite flow of ghosts, asymmetric confrontation, ghosts are invincible)
