Mystic Hotel. Under the Power of Sleep

You are a team of researchers from a scientific research institute, tasked with investigating a long-closed and mysterious project codenamed "Abode of Dreams". Once upon a time, this project was a leading direction in the study of the human unconscious and controlled dreams, but suddenly all research was terminated and the materials were classified. Recently, after many years of oblivion, your department was assigned to renew the research. The research institute sent the first group of specialists to inspect the area and collect relevant information. However, each member of this group was found unconscious at the doorstep of the house where the research was conducted. Your team must continue the work. You need to find out why the first group ended up unconscious and find a way to prevent this fate from repeating with you.
