It happened again. Or maybe it's the same thing happening again. I don't know.

The first time it was a year ago. I was in my apartment, the one by the park. I’d been dreaming, I think, but then I wasn’t. Or the dream was still there, but I was awake. My eyes were open. I could see my ceiling, the faint glow of the streetlight through the blinds. Everything looked normal. Too normal. I tried to move my arm. To scratch my nose. It felt like it wasn't attached to me, like it was made of lead. No, worse. Like it was stuck in a thick, invisible glue. I tried to speak, to call out, but my lips wouldn't part. No sound came out, just a silent scream inside my own head.

I wasn't scared at first. Just confused. It was like being trapped inside my own body. Then, the feeling came. A presence. Not a person, exactly. More like a heavy pressure on my chest. I couldn't breathe properly. It wasn't that my lungs were compressed, it was like the air itself was thick and I had to force it in. And this feeling of being watched. Not from the door or the window. From right there, in the room, behind my back. I could feel it. A cold, malevolent weight.

I don't know how long it lasted. A minute? Ten? It felt like an eternity. Then, just as suddenly as it started, it was gone. My arm moved. My chest felt light. I sat up, heart pounding, and looked around the room. Empty. The feeling of dread lingered for hours, a cold sweat on my skin. My girlfriend found me later, staring at the wall. I couldn't explain it. How do you tell someone you were awake but couldn't move or speak, and you felt a ghost on your chest?

I went to see Master Ming. Of course I did. He’s my friend. I told him everything, the details. He listened, nodding slowly. He didn't look surprised. He said, "Ah, Gui Ya Chuang. Ghost pressing the bed." He said it so casually, like it was a common cold. He explained that it's when your soul, your *hun*, separates a little from your body during sleep. A wandering spirit, an earthbound ghost, senses this and tries to get in, to take your place. It's a test. My *qi* must be weak, he said. Or the path from my bed to the door is blocked, creating a vortex of negative energy. He told me to move my bed, to keep a small bowl of salt by my head. To burn sandalwood incense before I sleep. He was kind, but his explanation was just… a story. A very old story.

So I asked my friend, Sarah, who’s a doctor. She just laughed a little, not at me, but at the phrase "ghost pressing the bed." She told me it's a classic case of sleep paralysis. The brain, she said, wakes up before the body. Your motor system is basically offline during REM sleep to stop you from acting out your dreams. Sometimes, that system doesn't switch back on right away. You're conscious, but you're paralyzed. It's a safety mechanism gone wrong. The hallucinations, the pressure, the feeling of a presence? All part of the brain's weird state, a mix of fear and dream logic. She said it’s very common, a glitch in the system. Nothing supernatural. Just a brain hiccup.

So now I have two stories. One from an old master about ghosts and souls. One from a doctor about brain hiccups. Both seem to fit the facts. Both explain what happened to me. So why do I still feel so uneasy?

I tried Master Ming's remedies. I moved my bed, I put out the salt. I even tried the incense, which made my room smell like a temple. The paralysis didn't happen again for a long time. But last week, it did. I was napping on the couch. Same thing. Eyes open, can't move, can't speak. The weight on my chest. The feeling of being watched. This time, there was no salt on the couch. No incense burning. But it still happened. So was it a ghost that ignored the salt? Or was Sarah right, and it was just my brain, which doesn't care about sandalwood?

I don't know which one is harder to believe. That the world is filled with invisible spirits trying to get into our bodies? Or that I am just a meat machine, and my brain can sometimes misfire in such a terrifyingly specific way? One feels mystical, the other feels cold and clinical. Both leave me feeling small. One in a universe full of spirits I can't see, the other in a universe of meaningless biological processes.

Maybe it doesn't matter why it happens. Just that it does. It’s a strange, liminal space. A moment when the solid world of waking life dissolves and you're left with pure, primal fear. A fear without a clear source. Is it the ghost? Or is it the fear of my own mind betraying me?

Master Ming would say the ghost is real, and I need to strengthen my *qi*. Sarah would say it's a neurological event, and I should maybe look into sleep hygiene. But I'm left here, in the middle. I don't know what to think. I just know I don't want it to happen again. Maybe I should try sleeping with the lights on. Or maybe I should just get a better pillow.
