I'm Locked up in a Mental Hospital

"No heroine, decisive killing" You wake up in the spiritual healing center, which is your new home. It was dark outside, and the old light bulbs in the room glowed dimly. As you can see, you are locked in this airtight room... And when you go through all the trouble to open the door, you find that countless bizarre events are constantly teasing your nerves... The constantly resurrected demons, mirrors that cannot reflect people, all-pervasive peeping, black shadows crawling and gathering on the ceiling... Everything is constantly approaching you, then - please make your choice.
