He half-closed his eyes and tried to suppress his random thoughts, but he questioned his eyes because of the dark shadows that kept flashing at the door. He pondered for a moment, barely supporting most of his body with his right arm, and then used the moonlight that vaguely filtered through the thin gauze curtains to look at the ajar door. There seemed to be dark shadows floating or surging there.
It seemed to be for no reason, and it seemed to involve something, such as some important information - unfortunately, he couldn't remember even a little bit, and he couldn't even tell whether it was reality or a dream. At first, he thought it was because he was under too much pressure at work during the day and the strong sense of oppression made him panic, which was why he woke up hesitantly in the middle of the night.
But he later discovered that the dark shadow was alive.
