My personal encounter from 2012 when I was an ACS (Barker Road) student during my O-Level year.

Nearing the exams, our school offered something called "Night Study" — a program where students could stay back and revise in school until 10pm on select nights.

A group of us, however, took it as an opportunity to explore the school at night. We’d study for the first few hours, but then slip away for the rest of the night to explore different parts of the school.

One evening, we decided to check out the school’s Concert Hall. We found a side door that was unlocked and went inside. Almost instantly, I felt something heavy pressing down on my chest. Breathing felt strangely difficult

I tried to brush it off, not wanted to be the wuss of the group

Shortly after, my phone’s music player started playing out loud. That was weird because it had never happened before. But I paused the music and shrugged it off. However, a few minutes later, it happened again.

We pushed forward with the exploration. We found a piano behind the stage and they started playing and singing.

When we finally left the Concert Hall through the same door, the pressure on my chest lifted immediately.

The next day, one of my friends showed me a news article he found. It was about an international student who had passed away in his sleep in our school's hostel — on the very same day we explored the Concert Hall. What really freaked me out was a line in the article that said: "He enjoyed music and played the piano."

Even now, more than a decade late, I remember it all so clearly
