Noisy (Ghost Story Title)

Just as I was getting used to my night shifts as a new employee, able to sleep from daytime into the evening. I suddenly woke up in the evening, but my body wouldn't move. I turned on the room light and saw my brother playing a game by the wall. I tried to call out, but no sound came out. Ah, I realized this must be sleep paralysis. Then I felt a pressure just below my chest, slightly above my lower abdomen. Hesitantly, I looked and saw a woman standing there, though I couldn't see her face. 'Whoa, seriously, stop it!' I thought, but since I couldn't speak, it ended with just thinking. Strangely, I wasn't scared. Trying to distract myself, I focused my attention on my brother, who was still playing his game. Maybe he got bored, because he started playing with the light's extension cord like a pendulum. Meanwhile, I was in no position for that... Then I noticed the positions: where I was sleeping, where the light was, and where my brother was. The cord, swinging like a pendulum, was passing right through the woman standing above me. I felt a mix of 'Was it really a ghost?' and 'The pendulum going through her is like a gag,' leaving me confused about how to react. Perhaps the woman couldn't stand it anymore, as she turned towards my brother and said, "Noisy!" My brother, surprised that I could suddenly speak, didn't react, but after a moment, he left the room. I thought, 'Why didn't you help me?' but there was nothing I could do.
